    Answer: 36pi cm^2

    Step-by-step explanation:

    Circumference = 2pi r

    Since circumference is 12pi

    r = 12pi/2pi

    r = 6cm

    Area = pi r^2

    = 6^2 pi

    = 36pi cm square.

    Answer: 36*pi cm

    Step-by-step explanation:

    Since the formula for the circumference is C=2*pi*r

    12pi=2*pi*r we can divide and get r=6 cm

    Then, we can use the formula for the area of a circle: Area=pi*r^2 and get Area=pi*6^2=36*pi cm.
