Answer:
4421 cubic feet
Explanation:
The volume of a cylinder is given by ...
V = πr²h
where r is the radius (half the diameter), and h is the height.
Using your numbers, the cylinder volume is ...
V = (3.14)(8 ft)²(22 ft) ≈ 4421.12 ft³
The maximum amount of water the tank can hold is about 4421 cubic feet.
