when trying to find squ. feet you have to find the area.
the area of a circle is half of the diameter squared times pi
half of the diamter is the radius therefore the area in squ. ft would be..
A = pi x r2

2826 square feet
The area of a circle is pi*(radius)^2. If the 8 ft is the diameter, the area is pi*(4 ft)^2~=50.27 ft^2 (ft^2 is square feet)
The diameter is twice the square root of (1000/pi) feet.
The circumference of any circle is (pi) x (the circle's diameter).
diameter = circumference ÷ π = 10 ft ÷ π ≈ 3.18 ft
