    Circumference is pi*diameter, so 94.2 / pi = 30, so the answer is C. 30 in

    The circumference = 2 pi radius

    94.2 = 2 * 3.14 * radius

    94.2 = 6.28 * radius

    94.2:6.28 = radius

    15 = radius

    radius = 1/2 diameter

    diameter = 2 * radius

    diameter = 2 * 15

    diameter = 30 in.
