The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.
A = π*(2.1)^2
A ≈ 3.14*(4.41)
A ≈ 13.8584 square miles
To calculate the circumference of the circle, we can use the formula C = 2πr.
C = 2*3.14*2.1
C ≈ 13.188 miles
Therefore, the area of the circle with a radius of 2.1 miles is approximately 13.8584 square miles and the circumference is approximately 13.188 miles.

I apologize for the mistake. Let's correct the calculations:
The area of a circle with a radius of 2.1 miles is calculated as:
A = π * (2.1)^2
A = 3.14 * 4.41
A ≈ 13.8501 square miles
To calculate the circumference, we use the formula:
C = 2 * π * 2.1
C = 2 * 3.14 * 2.1
C ≈ 13.188 miles
Therefore, the corrected area of the circle is approximately 13.8501 square miles, and the corrected circumference is approximately 13.188 miles. Thank you for pointing out the error.

I apologize for the mistake. Let's correct the calculations once again:
Given:
Radius (r) = 2.1 miles
Area of a circle:
A = πr^2
A = 3.14 * (2.1)^2
A = 3.14 * 4.41
A = 13.8474 square miles
Circumference of a circle:
C = 2πr
C = 2 * 3.14 * 2.1
C = 13.188 miles
Therefore, the corrected area of the circle with a radius of 2.1 miles is approximately 13.8474 square miles and the corrected circumference is approximately 13.188 miles. Thank you for your patience.
