Circle (with Pointed Edges)

[BenSCR]

How can I make a 'Circle' with pointed edges like in this photo?

Use the star tool (one of the shape tools) with a smallish difference between radii (select the tool and click once on the canvas to set parameters).

Another way would be Effect > Distort & Transform > Zig Zag …
