Conversion amoung three different volume units may be necessary.
231 cubic inches = 1 U.S. Gallon.
1 foot = 12 inches

Let's choose to put everything in inches to find the cubic inch volume:

Volume+=+pi%2Ar%5E2%2Ah, basic formula, r is radius, h is height

Volume+=pi%2A%2818%29%5E2%2A%286%2A12%29 in%5E3, includes converting the feet to inches

Volume+=pi%2A%2818%29%5E2%2A%286%2A12%29%2A231 in%5E3+%2A+gal%2Fin%5E3, includes converting cubic inches to gallons.
