Describe how you would like to measure the circumference of a cilinder using a thread and a meter rule

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

Explanation:

You first wrap the threat around the cylindrical object.At the point were the thread meets its beginning place a mark.Remove the threat and using a ruler measure its length ,this gives the outer circumference of the cylindrical object
