Approximating the area of a circle

Note: This is the output of the one the Math and Multimedia GeoGebra Tutorials. To view the step-by-step instructions in creating the worksheet below click here.


Adjust sliders r and n at the right hand slide of the GeoGebra applet window.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

1.) What do you observe about the relationship between the area of the circle as n increases?
2.) Vary the values of n and r and observe what happens. Based on your observations, what conjecture can you make?

  1. Thanks for the links explaining how to find area of a circle and how to use the formula for area of a circle, every thing is so valuable to teach circle geometry to high school students.
