Answer:

74 gallons

Step-by-step explanation:

Volume of water to be added (in ft3) = π[tex](1.25)^{2}[/tex](2.0)

                                                               = 9.8175 ft3 (5 s.f)

Volume of water to be added (in gal) = 9.8175 (7.5)

                                                                = 74 gallons
