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.
There are 5280 feet in a mile. An acre is 43560 square feet. The perimeter of an acre, in a square, is 208.71 feet.per side. So, each lap around one acre is 834.84 feet. 5280 divided by 834.84 gives us the number of laps to reach one mile walking around one acre of land, which comes to a little more than 6.32 laps.
