Acylindrical rain barrel with a diameter of 2.5 feet and a height of 3.5 feet is filled to a height of 1.5 feet. how many more gallons of water can the barrel hold? round your answer to the nearest whole number. (1 ft3≈7.5 gal)

how i am supposed to answer it: the rain barrel can hold about (blank) more gallons of water.

74 gallons

Step-by-step explanation:

Volume of water to be added (in ft3) = π(2.0)

                                                               = 9.8175 ft3 (5 s.f)

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

                                                                = 74 gallons

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

207/8 is the right
