Example:A conical container has a height of 2.3 feet and a base with a radius of 1.8 feet. Calculate the volume in gallons.
 Volume = (1/3) * π * R2* H
 Volume = (1/3) * 3.14 * 1.82ft * 2.3 ft
 Volume = (1/3) * 3.14 * 3.24 squared ft * 2.3 ft
 Volume = 7.8 cubic ft
 7.8 cubic feet * (7.48 gallons / 1 cubic foot) = 7.8 * 7.48 = 58.34 gallons
