To find the circumference \( C \) of a circle given the radius \( r \), you can use the formula:
\[
C = 2\pi r
\]
Given that the radius \( r \) is 97 m, we can substitute this value into the formula:
\[
C = 2\pi(97)
\]
\[
C \approx 2 \times 3.14 \times 97
\]
\[
C \approx 6.28 \times 97
\]
\[
C \approx 609.16
\]
Rounding to the nearest whole number, the circumference is approximately 609 m.
Therefore, the correct response is:
**609 m**
