The radius of a circular cylinder is the same as that of a sphere. Their volumes are equal. The height of the cylinder is?

4/3 times its radius
2/3 times its radius
Equal to the radius
Equals to its diameter

Correct Answer: 4/3 times its radius

Explanation:

∵ 4/3 πr³ = πr² h
⇒ h = 4/3 r
∴ Height = 4/3 times its radius.
