Question

What is the exact volume of a cylinder whose radius is 21 centimeters and whose height is 30 centimeters?

Answer 1

13,230$\pi$  is the answer, i just took the test!

Answer 2

The volume, V of any cylinder is given by:

$V=\pi r^2h$

Where, r is the radius of the cylinder

h is the height of the cylinder.

In our case, the radius of the cylinder is 21 centimeters and it's height is 30 centimeters. Therefore, it's volume will be:

$V=\pi(21)^2\times 30=13230\pi cm^3$

Thus, the answer answer, in terms of π is $13230 \pi$ cm³.
