Best Answer

Area of a Circle = (pi)(r^2)

Diameter = 2r

If the diameter of the circle is 12, then the radius has to be 6.

If the area of a circle is pi times the square of the radius, and the square of 6 is 36 (6x6), then the area of the circle is 36pi.

The circumference and area of a circle with a 17 ft diameter are:C = 53.4 ftA = 227 ft2

Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.

201.06ft2

Radius = diameter ÷ 2 Area = π x radius2 = π x (12 ÷ 2)2 = 36π ≈ 113 sq ft.

The area is 50.3 square feet.
