Question

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius.use 3.14 for pi and round your answer to the nearest hundredth.

Answer 1

Volume of the cylinder =
`254.34\,inches^3`

Explanation:

Diameter of the cylinder =
`6 \,inches`

Radius of the cylinder:

`(6)/(2) =3 \,inches`

Height :

`3* radius=3* 3\\=9\,inches`

Volume of the Cylinder=
`\pi * r^2* h`

`=3.14* 3* 3 * 9\\\\=3.14* 9 * 9\\\\=3.14 * 81\\\\=254.34\,inches^3`

The volume of the cylinder is:
`254.34\,inches^3`
