Question

A cylinder, a cone and a hemisphere have equal base and equal height. What is the ratio in their volumes?

• A. 3:01:02
• B. 1:02:03
• C. 3:02:01
• D. 2:03:01

Answer 1

The correct option is A

3:01:02

Let us assume that radius of cylinder, cone and hemisphere is r and as per question their height is also r.

So ratios of their volumes will be

$\pi r^{2}r:\frac{1}{3}\pi r^{2}r:\frac{2}{3}\pi r^3$

=3:1:2
