Question

the volume of two hemispheres are in the ratio 8:27 then the ratio of their radii is

Answer 1

Answer:

we know that volume of hemisphere is 2/3πr³

let the radii of first hemisphere be R

let the radii of second hemisphere be r

then

2/3πR³/2/3πr³=8/27

2/3π will cancel with each other

R³/r³=8/27

R/r=2/3

Therefore, the ratio of there radii is 2/3
