It very likely means 'radius'.===========================Answer #2:"Radius" is a good guess, but it could mean anything at all, and it's the job of theperson who wrote the question to make sure you know clearly what it means.
It refers to the radius of a circle which is half of its diameter.
When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
