Marks: +1, -0

The radii of the base of a cylinder and a cone are equal and their volumes are also equal. The ratio of their heights is

Solution:

(4) Let the radius of the cylinder and cone be r, and the heights of cylinder and cone be h

_{1}

and h

_{2}

, respectively. Now,

\π r^{2} h_{1}= {1}/{3} \π r^{2} h_{2} ⇒{h_{1}}/{h_{2}}= {1}/{3}
