The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.

Using the given radius of 2.1 miles and π ≈ 3.14, we can substitute these values into the formula:

A = 3.14 * (2.1)^2

A ≈ 3.14 * 4.41

A ≈ 13.8314

Rounding to the hundredths place, the estimated area of the circle is 13.83 square miles.
