    16 pi or approximately 50.24

    Step-by-step explanation:

    The area of a circle is given by

    A = pi r^2 where r is the radius

    r = d/2 where d is the diameter

    r = 8/2 = 4

    So plugging into the equation for the area

    A = pi (4) ^2

    A = 16pi

    Using 3.14 as an approximation for pi

    A = 16*3.14 = 50.24
