A chord touches two points on the circumference of a circle whereas a radius touches only one point from its center.

### How do you find the radius given the chord length?

If you are given a chord length of a circle, unless you are
given more information about the chord, you can not determine what
the radius of the circle will be.
This is because the chord length in a circle can vary from a
length of (essentially) 0, up to a length of double the radius (the
diameter).
The best you can say about the radius if given the chord length,
is that the length of the radius is at least as long has half half
the chord length.
