draw circles radius

Hello,

I have a serie of circles of different radius, i have divide each circle by a certain number of points, and i would like to connect the center with the points on each circle.

The problem I have is that when i use the line box and input center and divided point, it connects each center with all the divided points whereas i want to connect the each center with the corresponding radius.

See how messy it is when i connect centers to divided points

Please tell me if you don't understand what i want to do, i don't know if i'm clear enough

Thanks a lot
