To find the circumference of the circle using the formula \( C = \pi d \), where \( d \) is the diameter:
Given:
- Diameter \( d = 40 \, \text{cm} \)
- \( \pi \approx 3.14 \)
Now, substitute the values into the formula:
\[
C = 3.14 \times 40
\]
Calculating this gives:
\[
C = 125.6 \, \text{cm}
\]
So the final answer is:
125.6
