    64 * pi Or

    200.96

    Step-by-step explanation:

    C = 2*pi * r

    The object is to find r

    16 pi = 2*pi * r

    Divide by 2*pi

    16*pi/2pi = 2*pi/2*pi * r

    8 = r

    The area of a circle = pi * r^2

    Area = pi * 8^2

    Area = 64 pi

    That's one answer

    pi = 3.14 (about)

    Area = 64 * 3.14

    Area = 200.96

    This is the second possible answer.
