Muchos alumnos se preguntan como se le pudo ocurrir a alguien que un valor irracional como Π, podía tener algo que ver con la Circunferencia y su área.

En este ejercicio planteamos un polígono de n lados inscrito en una circunferencia.

Para obtener el verdadero valor de Π dividiremos el perímetro entre 2r (r = radio).
Observar que cuantos más lados tenga el polígono, más cerca estamos del verdadero valor de Π.

Te proponemos que aumentes el número de lados del polígono utilizando el deslizador n y que observes como la división Perímetro/2r es casi Π.

También podrás ver que cuantos más lados tenga el polígono, más cerca están su perímetro y su área de los valores de la longitud de la circunferencia y su área.
