To calculate the circumference of a circle, you can use the formula:

\[
\text{Circumference} = \pi \times d
\]

Where:
- \( d \) is the diameter of the circle.
- \( \pi \approx 3.14159 \).

In the image, the diameter \( d \) is given as 158 cm.

Now let's compute the circumference:

\[
\text{Circumference} = 3.14159 \times 158 \, \text{cm}
\]

I will calculate this for you.The circumference of the circle is approximately 496.4 cm, rounded to 1 decimal place.
