Best Answer

**Assuming a flat surface (no hills or depressions)**

**Area of a circle = π r2**

**Area of a circle = 3.14159 * radius square**

**Radius square = lineal meters * lineal meters**

**1 mile = 1,609 lineal meters**

**6 miles = 9,656 lineal meters**

**Area of circle with a 6 mile radius = 3.14159 * 9,656 * 9,656**

**Area of circle with a 6 mile radius = 292,920,754 square meters**

**1 Acre = 4,046.8564 square meters**

**Total acres in a circle with a 6 mile radius = 72,382.2947**

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.

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)

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

2433 acres, approx.

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.

50.9 acres approx.

Approx 2011 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)

The area in acres is 125,653 9.

Area = pi R2 = (9 pi) square milesEach square mile = 640 acres.The circle = (9 x 640 x pi) = 18,095.6 acres (rounded)

The area of a circle can be worked out by the formula πr2 , where r is the radius of the circle and π (pi) is the ratio of the circumference to the diameter (= 3.142 to three decimal places) So 3.142 × 122 = 3.142 × 144 = 452.4 square miles There are 640 acres in one square mile, so 640 × 452.4 = 289,530 acres In a circle of six miles radius, the area covered is 289,530 acres.
