@@efficientatif I tried this using the direct selection tool but cursor drags a segment of the circle with it. The only way I can remove the inner lines with the direct selection tool is if I press the cursor from outside the circle and highlight the points of the inner circle and delete. This removes the lines but also a segment of the outer circle.
for some reason I can't make dotted dashed lines... following the same setting as you but my lines come out line long ovals and dont turn into circles.... any help?
