Question

The cylinder shown has a radius of 3 inches. The height is three times the radius. Find the volume of the cylinder. Round your solution to the nearest tenth

Answer 1

254.5 Inches Cubed

Explanation:

Formula for Finding the Volume of a Cylinder:
`V=\pi r^2h`

The radius is 3 inches.

`r=3`

The height is three times the radius.

Multiply the radius by three to get the height.

`h=3*3\\h=9`

The height is 9 inches.

Use the formula to find the volume.

`\pi (3)^29= \pi (9)9=81\pi`

The exact volume is 81
`\pi` inches cubed.

`81 * \pi` ≈ 254.47

254.47 ≈ 254.5

The volume of the cylinder should be about 254.5 inches cubed.
