Explanation:

Step1: Recall diameter - radius relationship

The distance from the center of a circle to the edge is the radius $r$. The diameter $d$ of a circle is related to the radius by the formula $d = 2r$.

Step2: Substitute the given radius value

Given $r=3$ meters. Substitute $r = 3$ into the formula $d = 2r$. So $d=2\times3$.

Answer:

6 meters
