+1911 A spherical ball fits snugly inside a cylindrical jar, so that the ball touches the top and bottom of the jar, and the sides of the jar. The volume of the cylinder is $144 \pi.$ What is the difference between the surface area of the sphere and the lateral surface area of the cylinder?

LATERAL Surface area of sphere = pi * 2r * h but we know that h = 2r
= pi * 2r * 2r = 4 pi r^2
Surface area of a sphere = 4 pi r^2
so the difference between the sphere srface area and the lateral cylinder = ZERO
