Archimedes' Approximation of Pi
By increasing the number of sides in the polygon, the polygon's shape and area will approach that of a circle.
The area of the n-sided polygon will be n times the area of one of its triangles.
b is the base
h is the height
By rearranging the equation n⋅b represents the perimeter of the polygon. As n increases the perimeter of the polygon approaches the circumference of a circle.
Adjust slider to change the number of sides that the polygon has.
