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.
The area in square miles = 8,434,598.55 acres * 1 square mile / 640 acres. Calculate 8,434,598.55 acres * 1 square mile / 640 acres = 13,179.06 square miles. Draw a picture of a rectangular land mass, such as a rectangular farm plot. Suppose that a surveyor found that the parcel is 2325 feet long and 1584 feet wide.
