In Arcmap...I create a circle at a particular point in dd.  Then I move to a specified radius (or even type it in). 

The result is a circle where the points on its circumference are not exactly in the right place (and its not just an

offset due to mouse errors)...Example (all in dd):

pick center point -121.400648, 38.300225.  Move out to radius of 0.21037.  You get for NESW points on the circle:


     -121.626374              -121.175917


N-S should equal .42074 but it is .353

E-W should equal .42015 but is .450

There might be some mouse errors, but this is way off.   What projection issue have I missed?  I'm pretty

sure the altitude doesn't vary more than 200' in this whole area.
