Solution:

The circumference of a circle is expressed as

[tex]\begin{gathered} circumference=\pi\times d \\ where\text{ d}\Rightarrow diameter\text{ of the circle} \end{gathered}[/tex]

Given that the diameter of the circle is 13 meters, we have

[tex]d=13[/tex]

By substitution, we have

[tex]\begin{gathered} circmference=\pi\times13 \\ where\text{ }\pi=3.14 \\ thus, \\ circumference=3.14\times13 \\ =40.82 \\ \therefore \\ circumference\approx41\text{ meters} \end{gathered}[/tex]

Hence, the circumference of the circle, to the nearest meter, is

[tex]41[/tex]
