1,578,943 (cubic feet) = 11,811,313.9 US gallons
The volume (V) of a sphere equals 4 over 3 times 3.14 times its radius squared. One cubic foot of water equals 7.48 cubic feet. One meter equals 3.28 feet (I like working in feet instead of meters) Volume works out to be 499.234 cubic feet. 499 cubic feet times 7.49 gallons per cubic foot equals 3,734.529 gallons.
