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 height of cylinder = h
and height cone = H
Then, πr² h = 1/3 πr² H
⇒ h/H = 1/3 = 1 : 3
