Need hint how to automate copy in a circle

I want to rework this part of our old juicer and for that, I need to replicate the little slits around the center and I tried to work this by hand and it did not work. I wasn’t able to find the right function or a tutorial video. I would bet there is an easy feature that can support me. Can somebody help me to find the right way to work it. Thank you very much!

Use the move/rotate tool. Select the slit to be moved, goto the move tool, move the center dot to desired axis. tap on the little + symbol to duplicate the part/drawing element. move copy to desired degree and repeat. If many copies needed, repeat above a few times, stop and select those elements as a group and repeat above process.
