- 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

Answer 2

Answer:

To get the circumference, simply multiply the radius by 2π. So, the circumference can be found by multiplying 3 centimeter (1.2 in) by 2π. 3 centimeter (1.2 in) x 2π = 18.84 centimeter (7.4 in).
