See below

Step-by-step explanation:

Volume of cylinder ( the pool) = pi r^2 h

                     V = pi (12^2)(4.5) =         NOTE: RADIUS not DIAMETER

                             2035.75  ft^3  

2035.75  ft^3  *  7.48   gal / ft^3   =   15 227.42 gals

15 227.42  gal   *   $.02 / gal =  $ 304.55 to fill
