$\large \text{Circumference} = \pi \times \text{Diameter}$

The answers are in terms of pi. Meaning that since we know that circumference equals to $\pi \times \text{Diameter}$ or $D\pi$, you would need to have the diameter along with the $\pi$. 

For instance, if we want to find the circumference of a circle with the diameter of 2 and the question says it in terms of pi, then I would have my answer as $2\pi$.
