what is area of circle diameter 160 ft?

To find the area of a circle, you can use the formula ( A = \pi r^2 ), where ( r ) is the radius. The radius is half the diameter, so for a diameter of 160 ft, the radius is 80 ft. Therefore, the area is ( A = \pi (80)^2 = 6400\pi ) square feet, which is approximately 20,106.2 square feet when you use ( \pi \approx 3.14 ).
