A cone of height 24 cm and radius of base 6 cm is made up of modelling clay. A child reshapes it in the form of a sphere. Find the radius of the sphere and hence find the surface area of this sphere.
Given Cone height = 24 cm
radius of cone = 6 cm
The volume of clay will remain same hence
The volume of cone = Volume of sphere
(R = radius of the sphere)
The surface area of sphere
