Question 82

A right circular cylinderis circumscribing a hemisphere such that their bases are common. The ratio of their volumes is

Solution

Volume of cylinder = $$ \pi r^2 h $$

here h = r bases are common

Volume of hemisphere = $$ \frac{2}{3} \pi r^3 $$

Ratio , $$ \frac{2}{3} \pi r^3 $$ : $$ \pi r^2 r $$

= 2 : 3
