Given, the circumference of the circle, C=12π.

The circumference of a circle can be expressed as,


C=2\pi\text{ r}

Here, r is the radius of the circle.

Put C=12π in the above equation to find radius r.


\begin{gathered} 12\pi=2\pi r \\ r=(12\pi)/(2\pi) \\ =6 \end{gathered}

The diameter of the circle is,


\begin{gathered} D=2r \\ =2*6=12 \end{gathered}

Therefore, the radius of the circle is 6 and the diameter of the circle is 12.
