I am looking to draw a circle like below on Illustrator for a graph. I get as far as doing the circular lines, but I just haven't been able to effectively split the circles in to equally sized sections. I've tried drawing lines over them and divide the objects with the Path tool, but it's dividing it weirdly. I think the problem is that the object below is not one object but rather a lot of circles. I've also considered using the scissors tool, but that will be hard to get the parts equal and the negative space divisions in the same size for all.
Is there a better way to do this? I very much appreciate the help and suggestions.
