A tank is 8 3/4 ft. in diameter and 28 ft. in length.

The tank is a cylinder and is 2/3 full of petroleum.

Specific gravity of petroleum is .7 (7 times heavier than water).

Compute weight of petroleum.

Volume of cylinder: pi * r^2 * height or length.

3.1416 * 4.375 * 4.375 * 28 = 1683.70125 = 1684 cu. ft.

1684 * 2/3 = 1122.66666 = 1123 cu. ft.

1 cu. ft. of water weighs 62.5 lbs.

1123 * 62.5 * .7 = 49131.25 = 49131 lbs.

What parts are correct?
