Question

A sphere and cube are of same height. The ratio of their volume is ?

Answer 1

given sphere and cube have same height
that is die of cube=diameter of sphere
a=d
or a=2r
volume of sphere:volume of cube=(4/3)πr^3:a^3
=(4/3)πr^3:(2r)^3
=(4/3)πr^:8r^3 
=(4/3)(22/7):8
=(88/21):8
=(11/21):1
=11:21
