A right cylinder and a right circular cone have the same radius and the same volume. The ratio of the height of the cylinder to that of the cone is?

3 : 5
2 : 5
3 : 1
1 : 3

Correct Answer: 1 : 3

Explanation:

Let the heights of the cylinder and cone be h and H respectively.
∵ πr²h = πr²H / 3
⇒ h/H = 1/3
∴ h : H = 1 : 3.
So their heights are in the ratio 1 : 3.
