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* 30=13230\pi cm^3`

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