# Rolling a circle to find pi

## Objective: Explore the value of Pi

## 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 ?
