Circle+lab

__Purpose__ - What is the relationship between circumference and diameter?

__Graph__ - Diameter vs. Circumference

__Calculation__ -

1. Slope of line = change in y / change in x

2. Percent error = |Experimental value - True Value| / True Value x 100

__Questions__ -

1. What is the relationship between circumference and diameter?

2. What does the slope of the line indicate?

3. What can you say about the precision of your measurements?

4. How can you improve your results?

Conclusion- Write in CURSIVE 1. Restate your purpose or question.

2. List the relationship that was found and the formula.

3. Discuss how you can justify your result. (How do you know it is true)

4. Error analysis - make a statement about the precision and accuracy of your measurements.
