Question

The volume of this cylinder is 2700π(cubed)

Find the length of the radius, r.
Give your answer as a surd in its simplest form.
r ?
150cm is the height​

Answer 1

Given that,

The volume of the cylinder,
`V=2700\pi\ cm^3`

The height of the cylinder, h = 150 cm

To find,

The radius of the cylinder.

Solution,

The formula for the volume of the cylinder is given by :

`V=\pi r^2 h\\\\r=\sqrt{(V)/(\pi h)}\\\\r=\sqrt{(2700\pi )/(\pi * 150)}\\\\r=4.24\ cm`

So, the radius of the cylinder is 4.24 cm.
