So basically, you want the volume of a cylinder 6 inches diameter, 1 ft tall?

Well the formula for volume of a cylinder is

Where r is the radious and h is the height. The radious is half the diameter which is 3 inches. Putting the numbers in gives your volume at roughly 334 cubic inches. I don't know how to convert cubic inces into gallons, especially as an English gallon and an American gallon are different. However, I can convert it to litres and you can figure it from there I hope.

1 litre, is 1 decimeter cubed, which is 1000 centimeter cubed. An inch is 2.54 centimeters so a litre is 1000/(2.54)^3=61.02 cubic inches. You have about 334 cubic inches, so 334/61.02 = 5.5 litres. Hopefuly you can convert litres into gallons.

Hope that helps,

Kev
