Answer:
It is the longest one (20).
Step-by-step explanation:
The hypotenuse is the length opposite the right angle and between the legs. In this case it is the longest one.
The number of participants increased by a factor of 200 from 2010 to 2013.
The formula is A=4πr^2
Your answer should be 314 in^3
Look below
First, you solve inside the parenthesis. 13 + 7 = 20 and 12 + 4 = 16. then you do inside these []. 20 - 16 = 4. 16 divided by 4 = 4
Hope this helped.
