Question

3. Find the radius of a cylinder with a volume of 950 cm3
and a height of 10 cm.​

Answer 1

The radius of the cylinder is approximately 5.5 cm.

Explanation:

Given,

Volume of the cylinder =
`950\ cm^3`

Height of the cylinder =
`10\ cm`

Solution,

Let the radius of the cylinder be r.

Now, according to the formula of volume of cylinder;

`volume = pi* radius^2* height`

On substituting the given values, we get;

`950=pi* r^2* 10\\950=3.14* r^2*10\\r^2=(950)/(3.14*10)\approx30\\r=√(30)\approx5.5\ cm`

Thus the radius of the cylinder is approximately 5.5 cm.
