**How do you work out the circumference?**

Circumference of a circle

- For any circle with diameter, , the circumference, , is found by using the formula.
- C = π d.
- = π × 8.
- = 25.13 c m.
- Remember that, for any circle, the diameter is twice the radius, or d = 2 r .
- = 2 × 3.
- = 6 c m.
- C = π d.
