Since the circle rolls around another circle without slippage, we must make the connection that the arc length of the big circle and the little circle will be the same. 1. Arc length formula . s=r*t. 2. We can see . arc AC = arc FC. 3. So arc . AC = a*t. and arc . FC = a*t. 4. Angle ABC = t. and . Angle DEC = t. 5. We need to find some . angle n ................
