The radius and height of a cylinder are equal to the radius of sphere The ratio of the rates of change of the volume of the sphere and cylinder is

Here we used the concept of differentiation and the formulas of cylinder and sphere to find the ratio. Given that the ratio of the rates of growth of the sphere's and cylinder's volumes is 3:4, the ratio of the rates of growth of the cylinder's volume to that of the sphere's volume is 4:3.
