A circle with radius 1 rolls without slipping once around a circle with radius 3. How many revolutions does the smaller circle make?

Does it matter if the smaller circle rolls on the inside or outside of the larger circle?

(In reply to No Subject by Elisabeth)

Surely if the radii of these circles is in ratio 1:3, then so is the circumference,
This makes the answer 3 times.
i do agree with your second statement though, it matters not if the smaller circle is inside or outsoide the larger.
