Let radius of sphere be r1
Let radius of hemisphere be r2
If both have same volume then
(4/3)*pi*r1^3=(4/6)*pi*r2^3
(1/3)*r1^3=(1/6)*r2^3
Therefore (r1/r2) =cuberoot(1/2)
Let radius of hemisphere be r2
If both have same volume then
(4/3)*pi*r1^3=(4/6)*pi*r2^3
(1/3)*r1^3=(1/6)*r2^3
Therefore (r1/r2) =cuberoot(1/2)

vo. of sphere : vo. of hemisphere is equal
4/3*pie*R3 = 2/3*pie*r3
2/3*pie{2*R3=r3}
2*R3 = r3
R3/r3=2:1
ratio = 2:1
4/3*pie*R3 = 2/3*pie*r3
2/3*pie{2*R3=r3}
2*R3 = r3
R3/r3=2:1
ratio = 2:1
