To calculate the circumference of a circle, you can use the formula:

\[ C = \pi \times d \]

where \(C\) is the circumference and \(d\) is the diameter.

Given that the diameter \(d\) is 4.5 miles and using \(π \approx 3.14\), we can calculate:

\[ C = 3.14 \times 4.5 \]

Calculating this:

\[ C = 3.14 \times 4.5 = 14.13 \]

So the circumference of the circle is approximately 14.13 miles.

Therefore, the correct response is:

14.13 miles.
