Area and Perimeter
If an artificial grass company charges $12 per square meter of grass and you have a 20 square meter field, how much money would it cost to cover the area in artificial grass?
$240
$12 x 20 is $240.
Write a formula to calculate the surface area of a cylinder
2 x πr2 + c x h
2 x πd + c x h
What two terms are used when referring to angles adding up to 90 degrees and angles adding up to 180 degrees.
Complementary angles (90 degrees) Supplementary angles (180 degrees)
A dot at (3,4) translates 9 left and 6 down, what point is it at now.
(-6, -2)
Solve The Following: 5/4 + 3 ⅛
35/8 Or 4 3/8
If the straight side of a right handed triangle is 8 (a) and the base is 6 (b) what is the length of the longest side (c)?
C = 10
C = square root of a2 + b2. Meaning that it is 8 squared (64) + 6 squared (36) which equals 100. The square root of 100 is 10.
Explain why two cylinders that are the same height can have different surface areas.
One can have a much wider circumference.
Both an irregular and normal pentagon angles add up to how many degrees?
Pentagons add up to 540 degrees.
A point rotates from (9,8) 180 degrees clockwise, what is it at now?
(-9,-8)
Solve The Following: 3/23 ÷2/7
21/46
The length of Joe’s farm field is 20 meters by 15 meters. He estimates he can put 1 cow per 12 square meters, how many cows could Joe put in the field?
25
20 x 15 = 300 and 300/12 = 25.
Write the formula to calculate the volume of a cylinder
V = πr2h.
V = π(d/2)2h.
Angles around a point add up to what amount?
360
Two points reflect from (4,6) and (2,7) over the x axis, what are the coordinates now?
(4, -6) (2, -7)
Solve The Following: ½-⅓ x ¼ +⅕ ÷1/6/?-97/60
1 37/60
Billy went to the Monster Truck Mash. Billy measured that the line from one side of the tire to the other on the Super Slam circular wheel was 70cm, what is the circumference of the wheel?
The circumference is 219 centimeters
C=dxpie
C=70xpie
C=219
If a circular pool has a radius of 4 and a height of 6 what is the surface area of the pool?
251.33
Using 2πrh+2πr2 and applying 4 and 6 you will find the answer 251.327412287 (rounded to 251.33)
If the left side of a triangle has a 56 degree angle and the right side angle is 43 degrees, how long is the top?
The top of the triangle would be 81 degrees.
A triangle (3,4), (6, 4), (5,7) rotates 270 degrees clockwise. What are the coordinates now?
(-4, 3), (-6, 4), (-7, 5).
6/7 - ¾ x (⅗ + 2/10)
9/35
The distance around the circular kiddie pool at the Life Aquatic Centre is 10m. If they are putting paint at the bottom, how many cans would be needed to cover the whole pool if a can could cover 2m.
4 Cans Of Paint
30/π = 3.14. 3.14/2 = 1.58. 1.58 squared = 2.53 x π = 7.96. 2x4 = 8 meaning 4 cans of paint would be needed.
If Josh’s goodlife water bottle has a radius of 3 cm and a height of 10 cm what is the volume inside the bottle.
V = Πr2h meaning that it is 9 x 10 x pi. 90 x π = 282.74.
A right handed triangle has a right angle on the left side and a 50 degree angle on the right side. What is the top angle?
The top is 40 degrees
A square reflects over a diagonal line (0,0)/(1,1). The coordinates are (6,2), (3,2), (6,5), (3, 5). What are the new coordinates?
(2,6), (2,3), (5,6), (5,3)
⅔ ÷ (5/7 ÷ 3/6) + ½
