Project: Estimating the value of pi

1. Collect different cylindrical objects such as bottle tops, buckets, rods,
pipes, and related objects.
2. Use a piece of thread to measure and carefully record the circumference
and the diameter of at least 5 different cylindrical shapes.

3. Divide the circumference by the diameter obtained in task 2 and record
your answers to 5 decimal places.
4. Calculate the average value of the results obtained in task 3.
5. Estimate the value obtained in task 4 correct to 3 decimal places.
