Formula of a triangle:
Bh x 1/2 (basically dividing by 2)
Your base is the length on the bottom your height is that line in the middle of the triangle. Multiply those then divide by two to get the area always. But since its long and its a prism you have to multiply by 12.
Volume will always have the unit 3 in it and the measuring unit will depend on what is says for example in this problem its inches so its inches cubed (3).
Answer:
A: 15%
Step-by-step explanation:
First test:
15 ÷ 20 = 0.75
0.75 * 100 = 75%
Second Test:
18 ÷ 20 = 0.9
0.9 * 100 = 90%
90% - 75% = 15%
This is true. To find the circumference (the distance around the circle) you multiply the diameter with pi.
3 39/40 = 3.975
3 19/20 = 3.95
3 1/2 = 3.5
least to greatest : 3 1/2, 3 19/20, 3 39/40
Answer:
(5,12)
