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

12,196.8 ft

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.
