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? 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 would 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's who diameter was 75.00 cm?


What was the accuracy of this experiment?
