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

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

$3.14 \times r^2 \times 15 = 1,695.6$

$r^2 \times 47.1 = 1,695.6$

Divide by 47.1 on both sides.

$\frac{ r^2 \times 47.1}{47.1} = \frac{1,695.6}{47.1}$

$r^2=36$

Taking square root on both sides.

$r=6$

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