A circle of radius 8 rolls inside a semicircle with radius 25.  What is the distance the circle travels?

So the circle moves 15 units to the right,

 

BUT

 

if you want to see how much rotations

 

Calculate the circumference and then divide 15 by it.

 

If you don't understand anything feel free to ask
