Title : Graphing a Linear Relationship Objective : To verify the linear relationship between the circumference and the diameter of circular objects by taking experimental data and utilizing graphical techniques. Introduction : The distance around a circle is called its circumference. A simple experiment can be conducted to aid in understanding the formula for the circumference of the circle. Use a piece of string to measure the distance around a circular
