A circle with a radius of 75 feet has an area of 17671.458676442588 square feet. You calculate this by using the area of a circle formula, which is A=pi*r^2.
How many degrees does a circle have? 360 degrees.
The area of a circle can be found using the formula: A = Pi * radius2 , therefore a circle with a diameter of 1 metrehas a radius of 0.5 metre, so A = 22/7 * 0.52 = 0.785 squre metres.
Assuming that you mean a 4ft wide circle then the area is calculated using A = Πr2 Π = 3.142, r = 2ft = 24in A = 3.142 x 242in2 A = 1809.792in2
There are infinitely many lines of symmetry on a circle.
