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?

Well, it involves seeking the circumference, 2ðr.

So, the distance travelled by the smaller circle=The circumference of the larger one.

So, v(2ð(1))=2ð(3), where v=the number of revolutions, of the thing that we are looking for!

so, v=3 turns!

YES! I HAVE FINALLY SOLVED A QUESTION! VEHEHEHEEH!
