The edge of a cube is equal to the radius of a sphere. If the edge and the radius increase at the same rate, then the ratio of the increases in surface areas of the cube and sphere is

The side of a cube is equal to the diameter of a sphere. If the side and radius increase at the same rate then the ratio of the increase of their surfaces is

The side of a cube is equal to the radius of a shpere. If the side and the radius increase at the same rate, then the relation between the rates of change of surface areas of the cube and sphere respectively is

The side of a cube is equal to the radius of a sphere. If the side and the radius increase at the same rate, show that the surface area of the cube increases slower than that of the sphere.

The edge of a cube is equal to the radius o the sphere. If the rate at which the volume of the cube is increasing is equal to lambda , then the rate of increase of volume of the sphere, is

The edge of a cube is equal to the radius o the sphere. If the rate at which the volume of the cube is increasing is equal to lambda , then the rate of increase of volume of the sphere, is

Rate of increase in surface area of a sphere w.r.t radius is ……….

If the radius of a sphere ia equal to the height and radius of the cylinder then the ratio of the rates of increases of the volumes of the sphere and cylinder is
