Exploring Pi
Objective: Find the value of Pi or
Instructions: In each questions below
Set the DIAMETER (green segment) to the given value, then roll the circle to the end to show you a total distance around the circle, CIRCUMFERENCE, given its value in red.
You are required in the two questions to find the RATIO of the Circumference to Diameter.
1) What is the value of the C and ratio when d=6?
In other words given d=6 value of C=? Ratio : =?
2) What is the of C and ratio when d=4?
In other words given d=4 C=? Ratio is =?
3) Predict the value of Pi
What do you think the value of Pi will be when diameter is 1?
4) Conclusion of Pi
What can you define Pi as ?
