How to input a specific radius of a circle?
here is syntax to generate a circle but I am not sure what radius it has.
START(0.5,0.27)
ARC(CENTER=0.5,0.18) ANGLE=360

See ARC in the Help index. An ARC can be specified in several ways :
ARC TO (x1,y1) to (x2,y2)
ARC ( RADIUS = R ) to (x,y)
ARC ( CENTER = x1,y1 ) to (x2,y2)
ARC ( CENTER = x1,y1 ) ANGLE=angle

Can I say that radius is 0.02 in this case?
START(0.5,0.22)
ARC(CENTER=0.5,0.2) ANGLE=360

Yes. That is geometry.
