    So since 11/pi doesn't means 11 divided by pi but it means 11 pi

    circumference=2pir

    if circumerence=11pi

    2pir=11pi

    solve for r (radius)

    divide both sides by pi

    2r=11

    divide by 2

    r=5.5

    area=pir^2

    area=pi5.5^2

    area=pi30.25

    answer is area=30.25pi in^2
