Answer 1

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
