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.
