A circular area of 5 miles radius covers 50265.5 acres(to 1 dp) Area = pi*radius2, which with radius in miles will give you area as 78.53982 square miles, then multiply by 640, since there are 640 acres in 1 square mile.

The radius is 1.261 miles.
To calculate the area of a circle with a radius of 5 miles, you would use the formula A = πr^2, where A is the area and r is the radius. In this case, the area would be A = π(5)^2 = 25π square miles. Since π is approximately 3.14, the area would be approximately 78.5 square miles within a 5-mile radius.
