Question

The volume of a cylinder is 45 in 3. if the radius is 3in, whats the height?

Answer 1

`h=1.59 inch`

Explanation:

Volume of the cylinder=
`45inch^3`

Radius(r) of the cylinder=3 inch

To find height(h) of the cylinder:

Volume of a cylinder=
`\pi *r^2*h`

`45=3.14*3*3*h`

`45=3.14*9*h\\\\45=28.26*h`

`h=45/28.26`

`h=1.59 inch`

The height of the cylinder is :
`h=1.59 inch`
