To find the circumference of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter of the circle. Given that the diameter is 4.5 miles and using \( \pi \approx 3.14 \):
\[
C = 3.14 \times 4.5
\]
Calculating this:
\[
C = 3.14 \times 4.5 = 14.13
\]
So, the estimated circumference of the circle is **14.13 miles**.
