You are provided with a test – tube, thread and a meter ruler. Outline the steps you would use to measure the circumference and hence the diameter of the test – tube.

---

Closely wrap the thread 10 times around a cylinder.
- use the Meter rule to measure the beginning and the end
- Repeat three times and get the average length i.e the circumference
- Use the formulae ??/??= D to find the diameter
