The radius is 4 meters
From the formula for the circumference of a circle, given as:
[tex]C\text{ = 2}\pi r[/tex]We solve for the radius as follows:
[tex]\begin{gathered} C\text{ = 2}\pi r \\ 8\pi\text{ = 2}\pi r \\ r\text{ =}\frac{8\pi}{2\pi} \\ r\text{ = 4} \end{gathered}[/tex]Therefore, the radius of the circle is 4 meters
