Exploring Pi and Circle Properties




Measure and analyze the properties of circles to understand the significance of Pi (π).


  • Various circular objects
  • Measuring tape or ruler
  • Calculator
  • Notebook for recording data


  1. Measure the circumference and diameter of various circular objects.
  2. Calculate the ratio of circumference to diameter for each object and record the values in your notebook.
  3. Compare the calculated ratios to the value of Pi (approximately 3.14159).
  4. Analyze any discrepancies and explore potential sources of error in measurements.
  5. Present your findings in a report, discussing the significance of Pi and its applications in mathematics and science.
