To calculate the number of acres in a 1-mile radius, we first need to find the area of a circle with a radius of 1 mile. The formula to calculate the area of a circle is A = πr^2, where r is the radius. So, the area of a circle with a 1-mile radius would be A = π(1)^2 = π square miles. To convert this area to acres, we need to know that 1 acre is equal to 43,560 square feet. Since there are 640 acres in a square mile, the number of acres in a 1-mile radius circle would be approximately 640π 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)
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.
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
If the area is a circle with a four-mile circumference, the area in acres is: 814.72 acres.
12.732 (rounded)
Approx 2011 acres.
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
The area in acres is 125,653 9.
The circumference of a circle with a 21 mile diameter is 66 miles (approx).
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.
A 1 mile radius circle covers approximately 3.14 square miles, which is equivalent to 2,008 acres.
circumference of a circle = 2*pi*radius or diameter*pi
Circumference of the circle = 1 times pi in miles
To calculate the area of a circle with a circumference of 87 miles, use the formula: A = (πr^2)/4. First, find the radius (r) which is 87 miles / 2π = 13.8 miles. Then, calculate the area using the formula: A = π * (13.8)^2 / 4 = 188.5 square miles. Finally, convert 188.5 square miles to acres by multiplying by 640 (since 1 square mile = 640 acres), resulting in approximately 120,640 acres.
