The formula for the volume of a cylinder is V = pi r2h, or the area of the circular base x the height. In this problem, we also have to make sure to use the same units for all the measurements, since the diameter is given in inches and the height is given in feet. Converting to inches, the radius, r, is 11 inches (half of 22 inches) and the height, h, is 276 inches (12 inches x 23 feet). 3.14 approximates pi. Plugging all these values into the formula gives: 3.14 x 112 x 276 = about 104,863.44 cubic inches. Since a cubic foot contains 12 x 12 x 12 = 1728 cubic inches, dividing 104,863.44 by 1728 gives about 60.68 cubic feet.

A cylinder that has an 18-inch diameter and is 36 inches long has a volume of: 5.3 cubic feet.
Assuming a "1 inch cylinder" refers to a cylinder whose diameter is 1 inch, the volume is V = pi*r2*h = pi*12*(50*12) = 1885 cubic inches.
A 14-inch diameter by 20 foot long pipe has a volume of: 21.38 cubic feet.
The volume of a cylinder is pi*r^2*h. The radius of the cylinder is 1 inch, and its height (in inches) is 5232 in. Plug in the values, the answer is 5,232*pi cubic inches, or approximately 16,433.7 cubic inches.
9,651 cubic inches for a 32-inch diameter x 12-inch long cylinder.
2,181.66 cubic feet.
A 100-foot pipe with a 6-inch diameter has a volume of: 19.63 cubic feet.
7.854 cubic feet.
The washing machine has a volume of approximately 2.91 cubic feet.
