Someone help The question is to find the volume of the cylinder in terms of pi.
The formula for Volume is V=pi*R^2*H right? radius is 3.4m and the height is 11m So i got 399... around but none of those are the answer choices i know when questions ask in terms of pi, i always get confused can anyone help me please?!
A.) 127.16
B.) 74.8
C.) 432.34
D.) 63.58
P.S - pi is after each answer
1)D
2)B
3)A
4)B
5)B
6)D
7)C
8)A
9)A
10)B
11)B
12)B
Thank you E!
Maybe just to help more, since numbers change.

In other words, how many times pi is it?
V = pi * 3.4 * 3.4 * 11 = 127.16 pi
