ANSWER:

The circumference is equal to 37.68 units

Explanation:

The circumference of a circle has the following formula


c=2\cdot\pi\cdot r

We know that the radius is equal to half the diameter, therefore, we replace and we have:


\begin{gathered} r=(d)/(2)=(12)/(2)=6 \\ \text{replacing:} \\ c=2\cdot3.14\cdot6 \\ c=37.68 \end{gathered}
