What is the exact volume of a cylinder whose radius is 13 meters and whose height is 20 meters? Enter your answer, in terms of π

Hello!

The equation to find the volume of a cylinder is

$V = \pi r^{2} h$

V is volume
r is radius
h is height

Put in the values you know

$V = \pi 13^{2} * 20$

Square the number

$V = \pi 169 * 20$

Multiply

$V = 3380 \pi$

The answer is $3380 \pi$

Hope this helps!
