The formula for the circumference \( C \) of a circle is given by:
\[
C = 2\pi r
\]
where \( r \) is the radius of the circle.
Given that the radius \( r = 97 \) m, we can substitute this value into the formula:
\[
C = 2\pi \times 97
\]
Using \( \pi \approx 3.14159 \):
\[
C \approx 2 \times 3.14159 \times 97 \approx 609.329
\]
Rounding to the nearest whole number, the circumference is:
\[
C \approx 609 \, \text{m}
\]
Thus, the circumference of the circle is approximately **609 meters**.
