9 sq ft = 1 sq yard so 28 ft * 18 ft = 28*18 sq ft = 56*9 sq ft = 56 sq yards.

Area 36 ft diameter circle = pi x radius squared = 3.1416 x 18 ft x 18 ft = 1017.87 sq ft
If the diameter of the circle is 4 feet across the area is about 12.6 sq ft. You can check this by using the formula Area=Pi times the radius squared.

28 foot diameter A = 3.14 x 142 = 615.44 sq ft
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
9 sq ft = 1 sq yard so 28 ft * 18 ft = 28*18 sq ft = 56*9 sq ft = 56 sq yards.
441pi/4 sq ft
12 ft * 28 ft = 12*28 sq ft = 336 sq ft
132.7 sq ft, approx.
This would not be called a circle. IT would be called a ring. Sq Ft of outer ring - Sq Ft of inner ring = Sq Ft in between 113.04 - 12.56 = 100.48 sq ft
16 x 28 sq ft...
20 ft * 28 ft = 560 sq ft = 52.03 sq metres.
There's no way to express area in feet - it needs to be square feet. A circle of radius 12" has an area of pi sq. ft. ~= 3.141 sq. ft. A circle of diameter 12" has area pi/4 sq ft ~= 3/4 sq. ft.
200 x .28 = 56 dollars
