    SA=2pir^2+2hpir

    V=hpir^2

    given

    V=1458 and r=9, find h

    V=hpir^2

    V / (pir^2) = h

    1458 / (pi9^2) = h

    18/pi=h

    sub

    SA=2pir^2+2hpir

    given

    r=9

    h=18/pi

    SA=2pi9^2+2 (18/pi) pi9

    SA=2pi81+2 (18) 9

    SA=162pi+324

    the surface area is 321+162pi or aprox 832.937904 square inches
