    To solve this problem you must apply the proccedure shown below:

    1. You must apply the formula for calculate the area of a circle, which is:

    A=πr^2

    Where A is the area of the circle and r is the radius of the circle.

    2. You have that the diameter is 6 feet, then the radius is:

    r=D/2

    r=3 feet

    3. When you apply the formula shown above, you obtain:

    A=9π feet^2

    A=28.27 feet^2

    The answer is: 28.27 feet^2

    Circumference = 6 ft

    circumference = 2*pi*r = 6

    solve for r:

    r = 6 / (2*pi) = 0.9554 ft

    area = pi*r^2 = 0.9554*0.9554 * 3.14 = 2.866 sq. ft
