How many acres in circle of one mile circumference?

Answer 1

To find the area of a circle with a circumference of one mile, first calculate the radius using the formula for circumference, (C = 2\pi r). Rearranging gives (r = \frac{C}{2\pi} = \frac{1 \text{ mile}}{2\pi} \approx 0.159 \text{ miles}). The area (A) can then be found using (A = \pi r^2), which is approximately 0.079 acres. Thus, a circle with a one-mile circumference has an area of about 0.079 acres.
