The circumference \( C \) of a circle can be calculated using the formula:

\[
C = 2 \pi r
\]

where \( r \) is the radius. Given that the radius \( r \) is 17 cm, we can substitute that into the formula:

\[
C = 2 \pi (17) \approx 2 \times 3.14159 \times 17
\]

Calculating this gives:

\[
C \approx 2 \times 3.14159 \times 17 \approx 106.76 \text{ cm}
\]

Rounding this to the nearest hundredth place, we find:

\[
C \approx 106.76 \text{ cm}
\]

Thus, the answer is **106.76 cm**.
