Question

A cone and cylinder have equal bases and heights. Their volumes in the ratio of 

A) 1 : 3 

B) 3 : 1 

C) 2 : 3 

D) 3 : 2

Answer 1

Correct option is (A) 1 : 3

\(\frac{\text{Volume of cone}}{\text{Volume of cylinder}}\) \(=\frac{\frac13\pi r^2h}{\pi r^2h}\)

\(=\frac13\) = 1 : 3

Answer 2

Correct option is  A) 1 : 3
