Do we have any known values? What we would know at the outset of the problem?

anonymous · Answer

The question is asking: What is the correct order to find the circumference. Which above I posted the a/b/c order

austinl · Answer

That is correct.
$$C=2 \pi r$$
You would find the radius, multiply it by two. That would give you the diameter, which you would then multiply by pi.
