    Assuming the frame is a perfect circle

    and 3 inches wide indicates the diameter

    area of a circle=pi times radius^2

    diameter=2 times radius

    radius=1/2 diameter

    diameter=3

    radius=1/2 times 3

    radius=3/2=1.5

    area=pi times 1.5^2=2.25

    pi is aprox 3.14 so

    2.25 times 3.14=7.065 square inches

    the answer is 2.25π square inches or 7.065 square inches
