Calculate the volume of a dome-shaped tank/container that has the shape of a hemisphere (half sphere).
Half of the length's base equals the height in this type of tank. This calculator uses feet for measurements.
one US gallon of water = 8.34 pounds. one US gallon of diesel fuel = 7.1 pounds one US gallon of gas = 6 pounds
V = 2/3Πr³ where V is the volume Π = 3.14159265 r half the length of the tank base
