Sabemos que el área de un círculo es: A = πr². Pero esto es realmente difícil de probar.

Entonces cortamos el círculo en cuñas y colocamos la mitad de las cuñas boca arriba y mitad boca abajo.
Las piezas amarillas colgantes siempre "llenan" las áreas vacías del rectángulo con A = πr²

A medida que aumenta el número de cuñas, la línea verde azulado -> radio y las piezas colgantes comienzan a encajar dentro del rectángulo.
¿No es genial? ¡Mostrar esto matemáticamente se llama cálculo!
