A silo is a structure that is shaped like a right circular cylinder with a half sphere on top. The surface area S of a silo of height h and radius r (including the area of the base) is given by the polynomial equation Sequals2 pi rh plus pi r squared. Note that h is the height of the entire silo. A coffee grinder is shaped like a silo, with a height of 11 in. and a radius of 1 and one half in. Find the surface area of the coffee grinder. Use 3.14 for pi. h r
