The formula for the circumference \( C \) of a circle is given by:
\[ C = 2\pi r \]
where \( r \) is the radius of the circle. Given that the radius \( r = 5 \) meters, we can substitute this value into the formula:
\[ C = 2\pi \times 5 = 10\pi \]
Thus, the circumference of the circle is
\[ \boxed{10\pi} \text{ meters.} \]
