The capacities of two hemispherical vessels are 6.4 litres and 21.6 litres. The ratio of their inner radii is –

[ A ] $\sqrt2$: $\sqrt3$		[ B ] 2:3
[ C ] 4:9		[ D ] 16:81

Answer : Option B

Explanation :

The ratio of capacity of two hemispherical = 6.4 : 21.6
So, the ratio of their inner radii
= 3$sqrt6.4 : 21.6$
= 4 : 6
= 2 : 3
