Formula for area of a circle is pi times radius squared

Area = pi * (3 *3) = 9 pi

formula for volume is area times length

Volume = 9 pi * 12 = 108 pi or 339.292 cubic inches (rounding to nearest thousandth)

231 cubic inches in a gallon, so 339.292 / 231 = 1.465 gallons (rounding to nearest thousandth)
