How to get the radius of a circumference given some points

  1. Apr 6, 2015 #1
    Do you guys know of any program that can give me the radius of a circumference, if I input the cartesian coordinates of some points?

    its usually trivial enough to do by hand.
    if you have to do it a lot, you use a math scripting program like gnu octave.
    a lot depend on details... i.e. too few points and there will be no unique radius.
    niggle: a circumference does not have a radius, but a circle has both.
