To find the circumference of a circle, you can use the formula:
\[
C = 2\pi r
\]
where \( C \) is the circumference and \( r \) is the radius.
Given that the radius \( r \) is 16 kilometers, we can substitute this value into the formula along with \( \pi \approx 3.14 \):
\[
C = 2 \times 3.14 \times 16
\]
Now, calculate the value:
\[
C = 2 \times 3.14 = 6.28
\]
\[
C = 6.28 \times 16 = 100.48
\]
Therefore, the circumference of the circle is approximately **100.48 kilometers**, rounded to the nearest hundredth.
