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 64 â¦ 0, since there are 640 acres in 1 square mile.
If you draw a circle with a half-mile radius around a food plot, you encompass about 640 acres, or about one square mile. That means that you need at the very least one food plot per square mile, but that is far from ideal.
