circumference of smaller circle
c = (1/3) * 30(3.14)
c = 10(3.14)

c = 2(3.14)r
2(3.14)r = 10(3.14)
Divide both sides by 3.14
2r = 10
Divide both sides by 2
r = 5 <––––––

This question makes no sense, how are we meant to find a radius without any given measurement on the larger circle.

I think you're missing info. Like what's the radius of the larger.
If the larger's circumference is 3x the circumference of the smaller, then the radius would also be 3x the size (or the radius of the smaller is 1/3 that of the larger).
EDIT: What I said above is still true. Use that information and you can solve the problem.
