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.
One acre is equal to 43560 square feet, one side is equal to 208.7 feet, so the perimeter would be 834.84 feet. Your 1.5 acre yard would have a perimeter of 1252.26 feet and there is 5280 feet in one mile so you would have to make approximately 13 laps around the perimeter of your yard to accomplish a 3 mile walk. Hope this helps.
