Keeping in mind that, the diameter of A is 24, thus its radius is 12, and B's diameter is 22, thus its radius is 11.



how much is left?  well 2592π - 2420π, that much.

Container A is completely full while container B has nothing in it.

When container B is completely full after the pumping, the volume of water left in container A will be equivalent to the volume of container A subtracted by the volume of container B.

The volume of any right cylinder is  where r is the radius and h is the height of the cylinder.

The diameters of the cylinders are given. The radius is half of the diameters.
The radius of container A is 24/2, or 12. The radius of container B is 22/2, or 11.







Now, subtract the two volumes.



Rounding this to the nearest tenth of a cubic foot will give 540.1 cubic feet. Thus, container A will have approximately 540.1 cubic feet of water after container B is completely full.
