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
The area is 50.3 square feet.
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.
