    C = 14 pi inches

    Step-by-step explanation:

    The area of a circle is given by

    A = pi r^2

    49 pi = pi r^2

    Divide each side by pi

    49 pi/pi = pi / pi r^2

    49 = r^2

    Take the square root of each side

    7 = r

    The circumference is given by

    C = 2 * pi * r

    C = 2 * pi * 7

    C = 14 pi inches
