Question

What is the volume, in cubic in, of a cylinder with a height of 20in and a base radius of 2in, to the nearest tenths place?

Answer 1

251.2

Explanation:

The formula for the volume of a cylinder is
`\pi r^2h`. Plugging in your measurements...

Height = 20 inches.

Radius = 2 inches.

The volume is
`\pi2^2h`.

Simplification...

`\pi2^220 = \pi4(20)= 4\pi 20`.

`\pi` ≈
`3.14`

3.14 * 4 = 12.56

12.56*20 = 251.2
