The formula to calculate the circumference \( C \) of a circle is given by:
\[
C = 2\pi r
\]
where \( r \) is the radius.
Given that the radius \( r = 1 \) mile and using \( \pi \approx 3.14 \):
\[
C = 2 \times 3.14 \times 1
\]
\[
C = 2 \times 3.14 = 6.28
\]
Therefore, the circumference of the circle is approximately **6.28 miles** when rounded to the nearest hundredth.
