Best Answer

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.

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.

If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).

If the area is a circle with a four-mile circumference, the area in acres is: 814.72 acres.

1 mile * 35 ft = 4.2424.. acres.

An acre is a unit of area, and a linear mile is a measure of length, so they cannot really be compared. However, if you mean a square mile, there are 640 acres to a square mile.

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

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

I have this same question so I'll try to work it out and answer it: The perimeter of the circle is 5,280 feet. Area of circle = 3.14 times radius squared. We don't have the radius, 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. So we've basicly just reminded ourselves that there are 640 acres in 1 sq mile. But what about a circle mile? The percentage of a circle that fits in the smallest possible square is 78.6%. So finally we multiply .786 by 640 acres and get our answer. The number of acres in a 1 mile circle is............................................ 503 acres.

Area of a circle = (pi) R2 = (pi) (1)2 = (pi) square miles 1 square mile = 640 acres (pi) square miles = 640 (pi) = 2,010.62 acres (rounded)

50.9 acres approx.

Approx 2011 acres.

The area in acres is 125,653 9.

The surface area of a circle can be calculated using the formula A = πr^2, where A is the area and r is the radius. In this case, the radius is approximately 12 miles. Converting miles to acres, we know that 1 acre is equal to 43,560 square feet. Therefore, the surface area of the circle would be approximately π * (12^2) * 43560 acres.

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 640, since there are 640 acres in 1 square mile.

A circle with a mile radius has an area of pi sq miles.
