    Step-by-step explanation:

    Let r be the radius of the circle

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

    We know the area is 49 pi

    pi r^2=49 pi

    r^2=49 pi/pi

    r^2=49

    r=sqrt 49

    r=7

    The circumference of the circle is calculated as

    C = 2pi*r

    C = 2 * pi * (7)

    C = 14*pi cm

    pi=22/7

    C=14*22/7=2.22=44 inches

    so, C = 44 inches
