Refer to the following information for the next seven questions.

The following questions refer to information learned from your lab report.
When you graphed Circumference vs Diameter for your ten objects, which values were graphed as the independent variable?
 
When you graphed Circumference vs Diameter for your ten objects, what should have been your graph's ideal slope? 

When you graphed Circumference vs Diameter for your ten objects, what should have been your graph's ideal y-axis intercept? 

If your group's EXCEL graph had a slope of 3.09 and a y-axis intercept of -1.23, what should be the equation for your line? 

Using your group's equation from the previous question, what would you predict to be the circumference of an object whose diameter is 75.00 cm? 

Using the formula C = πD, what should have been the circumference of an object whose diameter is 75.00 cm? 

What was the accuracy of this experiment?
