The value of Pi
In this activity, we use the perimeter of the regular n-sided polygon to estimate the circumference of its circumcircle. When the number of sides of the polygon increases, the perimeter gets closer and closer to the circumference of the circle. Drag the slider to change number of sides of the polygon. Pay attention to the estimated value of pi (perimeter/diameter).
From this activity, what is the best estimation of the value of pi?
