6 spherical balls can be placed in a cylindrical tube. If we conclude that no space is left at top or bottom .let the radius and height of the sphere be "r" and "h" respectively . Find the ratio of the surface area of sphere and C.S.A of cylinder . If the ratio is in the form of a : b , then calculate a+b ?
