You can put this solution on YOUR website! First, you'll need to find the volume of the cylindrical tank. Then, you'll need to find the density (gallons/cubic foot) of water. Your answer will be the product of these two quantities.
Using: r = 12 ft. and h = 30 ft.
Using as an approximation. cubic feet.
Density of water:
7.48 gallon(U.S. liquid) per cubic foot.
Capacity of tank:
C = 101,465 gallons of water.
