    C = 14*pi cm

    Step-by-step explanation:

    The area of a circle is given by A = pi * r^2

    We know the area is 49 pi

    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

    sqrt (49) = sqrt (r^2)

    7 = r

    Now we need to find the circumference

    C = 2*pi*r

    C = 2 * pi * (7)

    C = 14*pi cm
