Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
A circle of radius r has a circumference of 2*Pi*r and an area of Pi*r*r, where Pi is the constant which is approximately 3.14159. Use the first equation to calculate the radius and then the second to calculate the area.
pi*25 = 78.5.
A = 804 square feet.
