Actually you don't need to use the resize tool on the circles. Al least in Illunstor v8-10 objects have bounding box handles that will move resize and rotate. So you don't need anything beyond the object select tool and ALT-SHIFT-Drag. Alt, copies the circle, Shift constrains it to resize from the center and Drag will resize. That way you don't have to worry about any math.
Overlord, the only reason I like to make the complete circle is just so I can see the math fulfull itself, making sure that I have the exactly even number of segments I want. If you rotate/copy at the wrong number you'll end up with radial lines that don't add up to 360-degrees. I just find it easier to double-check myself that way. But if you're good with the numbers you can divide it up and only make what you need to work with
Don't bother with Photoshop 7 unless you really need the new painting engine or healing brush foe editing images. I still use 6.01 on my PC, and I dont feel any loss. The vector stuff in PS doesn't hold an candle to Illustrator's capabilities.
