Si l'aire d'un cercle est 226,9806 cm2. Quelle est la mesure du rayon?​

Sagot :

Answer:

Rayon = 8.5cm

Explanation:

La formule de la zone d’un cercle est la suivante:

a = 3.1416 * rayon²

a = 226.9806

donc

226.9806 = 3.1416 * rayon²

rayon² = 226.9806/3.1416

rayon² = 72.25

√rayon² = √72.25

rayon = 8.5cm
