The formula to calculate the area of a circle is: A = πr², where A is the area and r is the radius.
Plugging in the given radius of 2.1 miles and using 3.14 as an estimate for π, we can calculate the area as follows:
A = 3.14 * (2.1)²
A = 3.14 * 4.41
A ≈ 13.8334
Rounded to the hundredths place, the estimated area of the circle is 13.83 square miles.
