Deleting part of a form using other foms

I am sorry but the title is not clear, I had trouble explaining it. Below is a screen of what I want to do, it will be easier to understand.

Basically, what I want to do is have all the parts in white transparent. I want to have the part in white delete the parts of the circle in the back.

please let me know if it is not clear;

Many thanks,
