Answer 5

I've never heard of such a term but I found an explanation of it here: http://mathworld.wolfram.com/RadicalCenter.html

Answer 6

Okay.
To explain this, I must first explain what 'radical axis' is:
Radical axis is the locus of a point, tangents drawn from which to two fixed circles are equal in length.




Now the radical centre of three circles is the point of intersection of the radical axes of three circles.
Here 'O' is the radical centre.

Now, a circle whose center is the radical center of any three circles, and is orthogonal to all three of them, is called the 'radical circle'!
