R means radius because the area of a circle = pi*radius2

radius
A little R in a circle usually means "registered trademark".
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
If you mean the circumference or "perimeter": C = 2(pi)r, where r is the radius of the circle
Symbol for "registered trademark"
that symbol means trademark
if you mean an arc, then pi x r
R means radius because the area of a circle = pi*radius2
