To solve the given problem we will use the equation for the circumference as a function of the radius:

$C=2\cdot\pi\cdot r^{}$

Substituting the given values, we have:

$\begin{gathered} C=2\cdot3.14\cdot9\operatorname{cm} \\ C=56.52\operatorname{cm} \end{gathered}$

From the solution developed above, we are able to conclude that the circumference of the given circle is C = 56.52 cm
