Assuming that a 100 ft circle is one with a diameter of 100 ft (ie radius of 50 feet),
area = pi*502 = 1963.5 sq feet
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
10,000 square feet.
Area of the circle in square feet = pi times radius squared
if the units for the 100 are in feet then 10,000 square feet
To find the square footage of a circle, you first need to calculate the area of the circle using the formula A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, so the radius is 2 feet. Substituting the radius into the formula, we get A = π(2)^2 = 4π square feet. Therefore, the square footage of a 4-foot circle is approximately 12.57 square feet.

The square footage of a circle that measures 159 feet in circumference is about 2,012 square feet.
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
Area of a circle = pi*radius2
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
If you mean a circle then its square footage formula is: pi*radius2
10,354.9 square feet.
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
