Question

Find the volume of a cylinder with a radius of 3 cm and a height of 7 cm.

Answer 1

`\large\boxed{V=63\pi\ cm^3}`

Explanation:

The formula of a volume of a cylinder:

`V=\pi r^2H`

r- radius

H - height

We have the radius r = 3cm and the height = 7cm. Substitute:

`V=\pi(3^2)(7)=\pi(9)(7)=63\pi\ cm^3`

Answer 2

Volume =
`63\pi cm^(3)`
