Question

a right circular cone, a hemisphere and a right circular cylinder on equal bases and have the same height. the ratio of their volume is?​

Answer 1

Step-by-step explanation:

radius of hemisphere=height of cone=height of cylinder

therefore,ratio of volumes=

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