El perimetro y la razon de pi

by Belen Alcantara Hernandez
1

El perímetro de un círculo es exactamente 3 veces su diámetro.

2

Si duplicamos el diámetro, el perímetro también se duplica.

3

π se obtiene dividiendo el área del círculo entre su diámetro.

4

Para cualquier círculo, la razón C/d siempre es π.

5

Si d=10 cm, el perímetro es exactamente 31.416 cm.

6

Un círculo con r=5 cm tiene mayor perímetro que uno con d=10 cm.

7

Si P=62.8 cm, entonces d≈20 cm.

8

El perímetro se puede calcular sin conocer r o d.

9

El diámetro es la mitad del perímetro.

10

Si P=12.56 cm, entonces r≈2 cm.
