    V = Bh; the base of a cylinder is a circle.

    V = πr2 h; r = 0.5 (30) = 15 feet

    V = 3.14 (15) 2 (48)

    V = 3.14 (225) (48) = 33,912 cubic feet

    33,912 cubic feet

    27 cubic feet in a cubic yard

    = 1256 cubic yards

    1256 x 202 = 253,712 gallons

    Step-by-step explanation:

    r=d/2 r=30/2=15ft

    h=48ft

    v=πr²h

    v=3.14*15²*48

    v=33912ft³

    cubic foot=0.037*33912

    cubic foot=1254.74cubic foot
