### How many gallons of water will it take to fill a 12 inch diameter cylinder 10 feet long?

To answer this question, you can calculate the volume of the
cylinder in cubic inches, then use the fact that a gallon is 231
cubic inches to convert to gallons. Cylinder volume is the cylinder
base area (the circle that is 12 inches in diameter) times the
height. Cylinder base area: 12 inch diameter, using pi x r2 =
3.14159 x 62 = 113 in2. Cylinder volume: 113 in2 x 10 ft x 12 in/ft
= 13560 in3. Conversion to gallons: 13560 in3 (divided by) 231
in3/gallon = 58.7 gallons.
