Circumference of the circle = 1 times pi in miles

circumference of a circle = 2*pi*radius or diameter*pi

314.159 sq miles

If the diameter is exactly 1 mile, then the radius is exactly 0.5 miles. Using A= (Pi)r2, we find that the area is exactly 0.25(Pi) square miles. This is approximately 0.7854 square miles.

Using the formula for the area of a circle, πr2, the area is exactly 0.25π square miles.That's about 0.785 square miles. Since π is an irrational number, the exact area cannotbe written with numerical digits alone.

If the circle's diameter is two miles, the area would be: 8042 acresA diameter radius of two miles is 12.5 square milesIf the circle's circumference is two miles, the area would be: 203.7 ac

1 sq mile = 640 acres area circle = π × radius² = π × (2.5 miles)² = π × 6.25 sq miles = π × 6.25 × 640 acres = 4000π acres ≈ 12,566 acres.

Use the formula for the area of a circle: area = pi x radius2. Then convert square miles to acres.

1 sq. mile = 640 acresArea of circle with circumference of 1 mile = (circumference2 / 12.5664)= 0.07957 sq. milesSo 0.07957 * 640 = 50.925 acres

There are 640 acres in a square mile.

The circumference of a circle with a 21 mile diameter is 66 miles (approx).

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)

That depends whether the "10-mile circle" refers to the circle's radius, its diameter, or its circumference. Assuming it is the diameter, divide it by 2 (to get the radius), then use the formula: area = pi x radius2.

There are 640 acres in one square mile.There are no acres in a mile.

1 square mile = 640 acres Area of the circle is π x 502 square miles = π x 502 x 640 acres ~= 5,026,548 acres
