That depends on the dimensions of the tub, and also on whether or not anyone has put any water in it.
It is not possible to answer the question. A gallon is a measure of volume in 3-dimensional space. The question provides information in only 2 dimensions so there simply is not enough information.
360' gallons of water!!!!!!!
You cannot define a volume with only two linear dimensions.
14.7 gallons of water.
Assuming the dimensions given are inside dimensions, the cylinder will hold 55.75 gallons - less if the dimensions given are outside dimensions.
...What are the dimensions of the pool?
Assuming all dimensions are in feet there would be 175,044 gallons.
A box with these dimensions can hold up to 16,921 US gallons of water.
Is the pool a circle? Do you want US gallons, or Imperial gallons?
If these dimensions are inches then the box will hold up to 124.7 US gallons of water.
A round pool with these dimensions and 4.5 feet deep has a volume of 265,500 gallons of water.
About 240 US gallons
A pool with these dimensions can hold up to 11,407.5 gallons of water.
About 29 gallons
It depends on the dimensions of the tube, but the question did not provide all of them.
