How many acres in a 4-mile circle?

Answer 1

To find the area of a circle, you can use the formula ( A = \pi r^2 ). A 4-mile circle has a radius of 2 miles (since the radius is half the diameter). Converting miles to acres, 1 square mile equals 640 acres; thus, the area is approximately ( \pi \times (2^2) \approx 12.57 ) square miles. Multiplying this by 640 acres per square mile gives roughly 8,064 acres in a 4-mile circle.
