Note: figure is not drawn to scale.

if r = 4 units and h = 13 units, what is the volume of the cylinder shown above?
use 3.14 for .

First you have to know the equation which would be V=πr^2h so then you would plug each number in to get V=(3.14)*(4^2)*(13) which would get you V=(3.14*16)*(13) which equals V=50.24*13 which gives you V=653.12 so your answer is
V=653.12
