Volume of Sphere and Hemisphere

Sphere: volume: SA

A sphere and a hemisphere have the same volume. The ratio of their radii is

The surface area of a cube is equal to that of a sphere. If x is the volume of the cube and y is the volume of the sphere, then what is x^(2) : y^(2) equal to?

If the radius of a sphere is halved, its volume becomes______times the volume of original sphere.

A sphere of maximum volume is cut out from a solid hemisphere. What is the ratio of the volume of the sphere to that of the remaining solid?

Show that the cone of greatest volume which can be inscribed in a given sphere is such that three times its altitude is twice the diameter of the sphere. Find the volume of the largest come inscribed ina sphere of radius R.

If the radius of a sphere is doubled, its volume becomes _______ times the volume of original sphere.

The volume and the surface area of a sphere are numerically equal, then the radius of sphere is
