Radius and geogebra.This question popped up in another thread and was answered there exactly. Let's see what geogebra can do.
1) Enter in the input box points (1,1),(12,1),(4,7),(9,7). We are done! Last edited by bobbym (20130313 22:38:55) In mathematics, you don't understand things. You just get used to them.
