Peri the winkle starts at the origin and slithers anticlockwise around a semicircle with centre (4, 0). Peri then slides anticlockwise around a second semicircle with centre (6, 0), and finally clockwise around a third semicircle with centre (3, 0). Where does Peri end this expedition?

After the trip around the second semi-circle, Peri ends up at (4, 0)
