The square footage of a circle that measures 159 feet in circumference is about 2,012 square feet.
Area of a circle = pi*radius2
If you mean a circle then its square footage formula is: pi*radius2
The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
10,354.9 square feet.

Area of a circle = pi*radius2 measured in square feet
Area of a circle = pi*radius2
Area of a circle = pi*radius2
Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2
