1 acre = 160 square rods A rod is a linear measure equal to 5.5 yards, or 16.5 feet while an acre is a measure of area equal to 4840 square yards, or 43,560 square feet.
We don't have the ra â¦ dius, but the sides of a square mile is 5,280. 640 acres are in a mile and 43,560 sq ft are in an acre, so when we multiply those figures we get 27,878,400 sq ft. So now we simply work the pie formula backwards..... 27,878,400 divided by 3.14 = 8,878,471 then we find the sq root of 8,878,471 which = 2,980 2,980 = radius.
