Dividing Part of a Circle

I know this question is from last year but I remember using a simpler method for creating a circle with 12 equal 30º angles using the Polar Grid tool (under the line segment tool). Once you select the tool and click the mouse on an open document you should get a dialog box that allows you to place the size of the object (i.e. 4"x4" to create a circle). In the next line, you can add how many concentric circles needed, if any. The last line you need to add information to is the number of radial dividers - this would be 7 in the case mentioned earlier. I have my students make a digital color wheel for reference that involves two concentric circles and 12 radial dividers. I have them add color to various segments so they need to use the Pathfinder tool to divide the sections so the Paint Bucket tool can be used in the various sections that were divided. This is the fastest way that I know to divide a circle. Sorry the answer is so late and I hope it is helpful. Thanks!
