The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
Well the formula for the radius of the square is radius squared * pi (3.14)So find the radius (which is half of the diameter. which is exactly half of the shape)and do the formula. end the answer with "m".
1 square mile = 640 acres.Area of a circle = (pi) (radius)2Area = (pi) (0.5)2 = 0.25 pi = 0.7854 square mile = 502.655 acres. (rounded)
The radius is 1.261 miles.
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
