When I cut out the triangle, the area in red of the circle is gone and the blue area is left behind.
For the semicircles, the not overlapped parts got cut out as they only have 1 layer (area in red), the shaded area in pencil is still around as it is the top layer of the big circle that has already been cut out.
The blue area is the part where it is not even touched
