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
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
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.
Approximately 58.42 (58.4180452) acres.
Approximately 0.065 (0.0649088843) acres.
