At first glance, this figure looks like it's made of fan-shaped, but looking at it, it's easy to see that it's a regular 5 concentric circles, with each concentric circle split from 4, 6, 8, and 10 sectors.
This picture is not very difficult to do, but still need a little skill and clear thinking I say my method, for you to refer to. Maybe you can do it in a quicker way.
