Math question need help?

George just won the lottery! He has decided to move into a new fancy house. In his old house, he had an aboveground, circular pool. The pool had a diameter of 20 ft. At the new fancy house, the pool is in-ground, has a circular surface and a cylindrical pedestal in the middle with a statue of someone George does not recognize (he doesn’t care though, the new house is awesome!). When he filled the new pool, he realized that the new pool took 2.4 times as long to fill as his old pool. Trying to figure out why this would be, he noticed that if the pedestal weren’t in the new pool, the radius of the new pool would be four feet more than three times the radius of the pedestal. Weird right? Anyway, what is the swimming area in the new pool? Oh, the pools are both uniformly the same depth, and please round to the nearest whole square foot.
