The ratio of volumes of cylinder and cone having same radii and heights A) 1 : 3 B) 3 : 1 C) 1 : 2 D) 2 : 1

Answer»

Correct option is (B) 3 : 1

Required ratio \(=\frac{\text{Volume of cylinder}}{\text{Volume of cone}}\)

\(=\frac{\pi r^2h}{\frac13\pi r^2h}=\frac31\) = 3 : 1

Correct option is  B) 3 : 1
