To find the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
where \( r \) is the radius of the circle.
Given that the radius \( r = 2.1 \) miles and using \( \pi \approx 3.14 \):
\[ \text{Area} = 3.14 \times (2.1)^2 \]
First, calculate \( (2.1)^2 \):
\[ (2.1)^2 = 4.41 \]
Now, substitute this value into the area formula:
\[ \text{Area} = 3.14 \times 4.41 \approx 13.8514 \]
Now, rounding this to the hundredths place:
\[ \text{Area} \approx 13.85 \text{ square miles} \]
Thus, the area of the circle is approximately 13.85 square miles.
