Question

The material of a cone is converted into the shape of a cylinder of equal radius. If height of the cylinder is 5 cm, then height of the cone is

Options

• 10 cm

• 15 cm

• 18 cm

• 24 cm

A cone is converted into a cone.

So,

Volume of cone = Volume of cylinder

`1/3 pi  R^2  h = pi R^2 xx 5 `

             `h = 15 cm`
