No. I would use linear units if measuring the swim distance or cubic units if measuring the volume of water. Square units might be useful to see how many people could use the pool before it got crowded but that would depend on whether they were there for swimming or splashing about.

You haven't provided enough information - what are the units of measurement (24 whats, feet, metres) and how deep is the pool...?
Meters
Your answer depends on your location. A pool in a Las Vegas building adds a different value -- and expense for upkeep, water and additional insurance, than does a pool in Toronto.
It is unlikely that the pool is 48 feet deep but there is no indication as to what units the depth is measured in. Consequently it is not possible to answer the question.
The answer will depend on the measurement units used. Also, it is necessary to know which number is the radius/diameter of the pool and which is its height.
Yes, units can be moved from one designation to another.
circumference = 2pi72 = 452.389 square units to 3 decimal places
An olympic sized swimming pool is 50 meter long and 25m wide using 8+2 lanes.
