Answer

J'ai calculé le rayon en divisant le diamètre par deux.

Step-by-step solution

3 steps

Identifier le diamètre donné.
Le diamètre ( $d$ ) était de $2,5 \text{ cm}$ .
Appliquer la formule du rayon.
Le rayon ( $r$ ) est la moitié du diamètre.
$r = \frac{d}{2}$ $r = \frac{2,5 \text{ cm}}{2}$ $r = 1,25 \text{ cm}$
Convertir le rayon en mètres.
$r = 1,25 \text{ cm} = 0,0125 \text{ m}$
C'est ainsi que j'ai obtenu $r = 0,0125 \text{ m}$ .
