Position mc around circumference of circle

I’m not so hot with this type of math. I’m trying to duplicate and position a movieclip (not animate around circle just place) around the circumference of a circle. The part I’m having a hitch with is respecting the movieclip’s angle. I’m setting the movieclip’s registration point at the bottom center. Here’s an image to show what I’m going for.

Thanks for your help guys.
