The problem asks for the circumference of a circle with a radius of 10 cm and suggests using \(\pi \approx 3.14\).

The formula for the circumference \(C\) of a circle is given by:

\[
C = 2 \pi r
\]

where:
- \(r = 10 \, \text{cm}\)
- \(\pi \approx 3.14\)

Substituting the given values:

\[
C = 2 \times 3.14 \times 10
\]

\[
C = 62.8 \, \text{cm}
\]

### Answer:
The circumference of the circle is **62.8 cm**.
