Drawing a circular object

Hello,

I need a little help with drawing a circuler object like this (did it in Paint):I had the idea of doing multiple segmented circles, then deleting whatever parts I don't need and connecting the remaining segments with straight lines. Unfortunately, I don't really know how to do this. The only help I got from the Internet so far was how to add nodes on the ring, but it seems the Delete Virtual Segment tool works a bit differently (maybe because adding nodes was in Curves mode?)

So all in all, I'm a total newbie in this. Help is appreciated.

Cheers
