Circle Test


  • was given today

  • if you were absent, it is YOUR responsibility to see me BEFORE class begins to make this up.

  • Once class begins, your opportunity to make it up ceases to exist

9.1 Areas of Rectangles and Parallelograms PDF



  • please read the first 2 pages of the PDF

  • from your reading, you will have your first THREE flashcards for the Area Chapter

  • Flashcard #1: base and height of a figure are ALWAYS -?- to each other

  • Flashcard #2: The area of a rectangle is given by the formula -?-, where A is the area, b is the length of the base, and h is the height of the rectangle.

  • Flashcard #3: The area of a parallelogram is given by the formula -?-, where A is the area, b is the length of the base, and h is the height of the parallelogram.

  • then complete (1-30) all

  • if you need clarification of how to complete these problems and/or want verification that your flashcards are correct, go section #11.3 of your book and read pgs 763-766

Circle Test is tomorrow!

Circle Pre Test again


  • please make sure you do your work in boxes all nice and neat with highlighted answers

  • set a timer for 80 minutes

  • make sure you know how to locate the center of a circle by construction

  • reminder to get to class AS SOON AS POSSIBLE after the first bell rings

  • the test is 46 questions plus one construction

  • you will NEED EVERY SINGLE SECOND possible so don't lolly gag in between classes

  • I will not pass out the first test until EVERYONE is ready with an answer sheet, a pencil, calculator, and construction tools out on their desk

  • so please do not be the one everyone gives dirty looks to because you waited until the last minute to get to class and when the bell rings, you're still fumbling for your pencil because I will NOT pass out any tests until EVERYONE is ready!

  • you will be handing in TWO sets of the circle pre test tomorrow so make sure you have two stapled sets in the inbox BEFORE the bell rings otherwise, you will be holding up the beginning of the test!!!

7.7 PDF


  • (1-18) all

7.6 PDF again



  • yes, I am reassigning these word problems because I KNOW that you didn't know how to do them

  • now that you know the answers, see if you can work your way backwards to solve the problems

  • remember, that distance = (rate)(time) and rpm means revoultion per minute

  • so, 100 rpms means 100 revolutions per minute or the wheel goes around 100 times in 1 minute

  • 1 revolution = circumference of the circle

  • so 5000 rpms = 5000 circumferences

Circumference Investigation


  • make a chart with 4 columns: Name of object, Circumference, diameter, C/d

  • find a round object in your house

  • Examples: top of a cup, top of a bowl, bottom of tupperware container

  • then take a piece of string and wrap it around your round object

  • using a cm ruler, determine how much string it took for you to wrap it around your round object EXACTLY one time

  • then determine the length of your diameter using the knowledge you obtained in class today

  • then put this information in your chart

  • repeat this for at least 3 more round objects in your house

  • to determine the answer to your last column, you must divide your circumference by your diameter. do you notice anything special about this number for all 4 of your round objects?

  • call a couple of friends and see what their results are....

  • be ready to discuss your results in class tomorrow

  • everyone MUST share one of their 4 examples with the class tomorrow

Trig Test


  • was given in class today

  • if you missed it, it is YOUR responsibility to come see me BEFORE the bell rings to make this up. Once the bell rings, your opportunity to make it up ceases to exist

Ch 10 Vocabulary



  • make flashcards for all 30 ch 10 vocabulary words on pg 750

  • there are 30 words

  • some are quick and easy so it's not as much as you think it is

10.1 and 10.2



  • please read AND understand ALL of the examples in these 2 sections.

  • I am not formally assigning any HW problems for these 2 sections but you should try some odd problems for each example to be sure that you understand the reading and examples

  • I will begin tomorrow's class with the assumption that you know and understand how to do sections 10.1 and 10.2 so it is IMPERATIVE that you read and understand the examples in these 2 sections

Trig Pre Test






  • complete this 3 times! once for Friday night, once for Saturday night, and one more time for Sunday night. 3 times in a row creates a pattern of success!!!! =)



  • that means you are turning in 4 sets to me on Monday (1 that we did in class and the 3 that you are doing this weekend)!

  • don't forget we did another example of vectors in class today so you have to do that one as well!

  • for those of you who didn't copy it in class, here it is again....

  • #15 (second example): Geomvannie is flying his Cessna on a heading in the figure at the right (you should have copied the picture of the parallelogram!) if not, you will have to recreate it yourself!). His instruments show an air speed of 130 mph (air speed is the speed of a plane as it flies in still air, that is, ignoring wind). There is a 20 mph wind intersecting the path of the plane as shown. What is the speed of the plane (its ground speed). What is its direction?



Water Bottle Caps







  • please save the plastic caps from your water bottles



  • a student is trying to collect 1,000 of them so a little girl with cancer can receive a free round of chemotherapy

Right Triangle Test


  • was given today

  • 135 points

  • if you were absent, it is YOUR responsibility to see me BEFORE class begins to make up this test. Once class begins, your opportunity to make this up ceases to exist

Trig Pre Test Word Problems (round all answers to the nearest tenth!)


(make sure you do your work in nice pretty boxes like the Student A example I showed you in class. I will be collecting this so make sure it is done! You will be taking the 2nd half of the Trig Test tomorrow so use the following problems to prepare for it!)



  1. Find the area of a triangular plot of land measuring 12 ft by 22 feet by 15 feet.

  2. A tree is growing vertically on a hillside that is inclined at an angle of 6 degrees to the horizontal. The angle of elevation to the sun is 52 degrees. If the tree stands 80 feet tall, how long is the shadow that it casts upon the slope?

  3. The angle of elevation from a ship to the top of a 90 meter lighthouse on the shore is 17 degrees. How far is the ship from shore?

  4. Peter is flying a kite with 125 meters of kite strung out. His kite makes an angle of 47 degrees with the level ground. How high is the kite?

  5. A 27 meter pole is leaning against a wall. The foot of the pole is 6 meters from the wall. Find the measure of the angle the pole makes with the ground.

  6. Smokey the Bear is an employee of the US Forestry Service and has been instructed to measure the heights of the taller trees in his sector. Using a transom, he measures the angle of elevation of the first tree to be about 63 degrees. He walks 44 paces to the base of the tree. If each pace is 0.8 meters, how tall is the tree?

  7. Air traffic controller I. C. Plains must quickly caluclate the height of an incoming jet. To do this, he records the jet's angle of elevation to be 16 degrees. If the jet signals that its land distance (aka distance on land aka ground distance) is 108 km from the base of the control tower, calculate the height of the plane. (ignore the height of the tower)

  8. An operator at the top of a lighthouse sights a sailboat. the point from which the sighting is made is 37 meteres above sea level. The angle of depression of the sighting is 22 degrees. How far is the boat from the base of the lighthouse?

  9. A support wire is attached to the top of a 115 meter radio tower. The wire is 215 meters long. Find the measure of the angle of elevation of the wire from the ground to the top of the tower.

  10. Find the measure of angle B in triangle ABC given the measure of angle A is 32 degrees, AC = 56 cm and BC = 45 cm.

  11. Find the area of triangle ABC in problem #10.

  12. Find the perimeter of triangle ABC in problem #10.

  13. Find the length of side DE in triangle DEF if given the measure of angle F is 72 degrees, DF = 53 and EF = 44.

  14. Find the area of traingle DEF in problem #13.

  15. Suppose you are canoeing due east across a river at 4 miles per hour. If the river is flowing south at 3 miles per hour, what are the resultant direction and speed of the canoe?

  16. Ms. Chan, while searching for her golf ball in the trees, spots a large cone of wood chips. She determines that the height of the cone is 10 meters and the slant height is 14 meters. What angle does the wood chip pile make with the ground? What is the circumference? Use pi = 3.14
