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

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.
