1.) Move slider r below to adjust the radius of the circle.

2.) Move slider n and observe what happens.

3.) Make a conjecture about your observations

The area of a circle can be approximated by inscribing and circumscribing a polygon with n sides. As the number of sides of the inscribed/circumscribed polygon increases, their areas approach the area of the circle.
