Ok, I am having some trouble with 24. If someone could help me out, that'd be great.

A circle can be drawn through points X, Y, and Z. XW=8, YW=6, ZW=12.

Find the radius of the circle, and the distance from the center to point W.

I know the answers, 5 root 5, and root 29, respectively. The problem is that I am having some trouble reaching those answers.

Thanks! The problem is attached as well.
