The hot tub is a cylinder. The Volume of a cylinder is given by V=pi%2Ar%5E2h, where r is the radius of the base and h is the height of the cylinder. In this case, r=d%2F2=12%2F2=6 and the height is equivalent to the depth, so h=4.

Putting it all together:

V%5BHT%5D=pi%2A6%5E2%2A4=36%2A4%2Api=144%2Api cubic feet. This is the exact answer. If you need a numeric approximation, use the pi key on your calculator, but remember to round your answer to the nearest cubic foot because your given dimensions were expressed to the nearest foot and you can't have an answer that is more precise than the least precise given measurement.

The calculator says: 452.38934211693022633862064719225, but your answer must be 452 cubic feet.
