Surface area of a sphere and cube are equal. Then find the ratio of their volumes.

Surface area of a sphere is

The surface areas of two spheres are in the ratio 1:4 then, ratio of their volumes is

Side of a cube and diameter of sphere are equal, then the ratio of their volume will be

The volume and surface area of a sphere are numerically equal. Then the volume of the smallest cylinder in which the sphere is exactly kept

The sum of the surfaces of a sphere and a cube is given. Show that when the sum of their volumes is least, the diameter of the sphere is equal to the edge of the cube.

If the rates of increase of side of a cube and radius of a sphere are equal and rates of increase of their volumes are in the ratio 2 : 1, then the ratio of the squares of side and radius =

Surface area of a sphere is ……….. sq. units.

The percentage error in surface area of a sphere is 6% then find the relative error in volume

The lateral surface area of a cylinder is equal to the curved surface area of a cone. If their base be the same, find the ratio of the height of the cylinder to slant height of the cone.
