This applet illustrates the circumference of a circle by wrapping a string around it.[br][list=1][*]Drag the blue point to change the diameter of the circle. A circle of diameter 4 units have been done as an example[/*][*]Measure the circumference. [/*][*]Calculate the ratio of the circumference to the diameter(enter "=" followed by "circumference/diameter").[/*][*]Repeat the process for 4 distinct diameter values[/*][*]Compare the ratio to the pi value from the calculator. How close are your approximations of pi?[/*][/list]
