Question

The volume of a cylinder can is 1.54 litre and area of base is 77cm^2 Find its height​

Answer 1

The height is 20 cm.

Explanation:

First, we have to know that the volume formula is V = πr²h and the base area of cylinder is a circle. So we can let πr² be 77 cm² . Then we have to substitute the following values into the formula :

`v = 1.54 \: l`

`v = 1540 \: {cm}^(3)`

`v = \pi * {r}^(2) * h`

Let πr² be 77,

Let v be 1540,

`1540 = 77 * h`

`77h = 1540`

`h = 1540 / 77`

`h = 20 \: cm`
