Question

Helppp how do u do this and whats the answer

Answer 1

Given:

Volume of cylinder = 1,695.6 cubic meters.

Height of the cylinder = 15 m

The value of the π = 3.14

To find:

The length of the radius.

Solution:

Volume of the cylinder = πr²h

`\pi r^2h = 1,695.6`

`3.14 * r^2 * 15 = 1,695.6`

`r^2 * 47.1 = 1,695.6`

Divide by 47.1 on both sides.

`$( r^2 * 47.1)/(47.1) = (1,695.6)/(47.1)`

`r^2=36`

Taking square root on both sides.

`r=6`

The length of the radius of the cylinder is 6 meter.
