ANSWER


h= 4in.

Step-by-step explanation

The volume of a cylinder is calculated using the formula;


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

It was given that, the cylinder has a radius of 2 inches and a height of 3 inches.

This implies that,


v = \pi * {2}^(2) * 3


v =12 \pi

The volume of a cone is given by


v = (1)/(3) * \pi {r}^(2) h

The cone has a radius of 3 inches:


v=(1)/(3) * \pi * {3}^(2) h


v=3 \pi h

The two volumes are the same:

This implies that,


3 \pi h = 12\pi

Divide both sides by 3π


h= 4in
