Answer: Pi · 2r

Step-by-step explanation:

The standard formula to find the circumference of a circle is Pi times the diameter of the circle. The diameter is 2 times the radius, which is what you're going to use in the formula.

So instead of Pi times the diameter, we have Pi times 2 times the radius. Thus, the formula is Pi · 2r.
