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.
Name: terri Question: How many acres are in a square mile? Hi Terri, In farming communities a square plot of land which is 1 mile by 1 mile is referred to as a section of land. It contains 640 acres. A section is usually divided into four equal parts which are called quarter sections, and this is the size plot that farmland is typically sold in. Each quarter section consists of 160 acres.
