Rolling a circle to find pi
Objective: Explore the value of Pi
Exploring Pi
Objective: Find the value of Pi or [math]\pi[/math][br][br]Instructions: In each questions below[br][b]Set the DIAMETER [/b](green segment) to the given value, then [b]roll the circle [/b]to the end to show you a total distance around the circle, [b]CIRCUMFERENCE[/b], given its value in red. [br][br]You are required in the two questions to [b]find the RATIO of the Circumference to Diameter.[/b]
1) What is the value of the C and ratio when d=6?
In other words given d=6[br][br] value of C=? [br] Ratio : [math]\frac{C}{d}[/math]=?
2) What is the of C and ratio when d=4?
[br]In other words[br]given d=4[br][br]C=?[br]Ratio is [math]\frac{C}{d}[/math]=?
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 ?
