Well, isn't that a happy little question! To find the square footage of a circle, we first need to know the radius. Once we have the radius, we can use the formula A = πr² to calculate the area. Just remember, there are no mistakes, only happy accidents!

If this circle is 28ft then:
Area of a circle = pi time r2
A diameter of 28 feet means a radius of 14 feet
Area = pi times 196 or 615.75 square feet
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
