The UCSMAN command shows all of the named UCS co-ordinate systems in a drawing.
Just type UCSMAN into the keyboard followed by enter key as with all keyboard entry.

Look for the knowledgesmart UCS and make it current. 

When you draw your circle, you can use absolute co-ordinates 0,0 as these represent the origin of the UCS in this scenario. 

Feed in the radius value of the circle when prompted.
