A circle with an 8-inch diameter has a perimeter of 25.1 inches.
Area of circle: pi*2.75 squared = 23.758 square feet to three decimal places
There are 100*pi square inches in a 20 inch diameter circle
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of the circle (which is pi times radius squared).
