To calculate the area of a circle, you can use the formula:
Area = π * (radius)^2
Given that the radius is 2.1 miles and the approximation for π is 3.14, we can substitute these values into the formula:
Area = 3.14 * (2.1)^2
Calculating this, we get:
Area = 3.14 * 4.41
Area ≈ 13.814
Therefore, the estimated area of the circle with a radius of 2.1 miles, rounded to the hundredths place, is approximately 13.81 square miles.

Apologies for the previous incorrect calculation. Let's reevaluate it correctly.
The formula for the area of a circle with a radius (r) is given by:
Area = π * r^2
Using an approximation of π as 3.14 and a radius of 2.1 miles:
Area = 3.14 * (2.1)^2
Area = 3.14 * 4.41
Area ≈ 13.8474
Approximating the answer to the hundredths place, the estimated area of the circle is approximately 13.85 square miles.
