The objective is to complete the following table given that the diameter $(d)$ of the circle is equal to $18\pi$. A condition to round the final answer into two decimal places is also given.

$\begin{array}{ | c | c | c | } \hline \text{radius}(r) & \text{diameter}(d) & \text{Circumference}(C) \\ \hline \\ & 18\pi & \\ \\ \hline \end{array}$

Table 1. Table of interest.

To complete the table above, we need to look for the diameter$(d)$ and circumference$(C)$ of the given circle. Figure 1. Circle of interest.

Figure $(1)$ represents the given circle with its corresponding notations.
