If the maintenance men are going to paint a spherical water tower whose radius is 30 feet and each gallon of paint covers 150 square feet of metal, how many gallons of paint must they have to give the tower one coat of paint?
-----------
Area of a sphere = 4*pi*r^2
= 4pi*900 = 3600pi
=~ 11310 sq ft
11310/150 = 75.4 gallons
