# Thread: Please help with geometry circle problem!

1. ## Please help with geometry circle problem!

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.

Guys?

I don't think there's enough information given in the question tbh...

I know why you would think that, but I am positive that there is a solution. Thanks though.

the center of the circle is going to be equidistant from X and Z. So what's that tell you about it's x coordinate.

Once you find that you have to find the y coordinate of the center by ensuring that the distance from the center to X is equal to the distance from the center to Y.

see if you can work it out now.

use coordinate geometry.
xz is the x axis
perpendicular bisector of xz is the y axis
write the equation of xy and its perpendicular bisector.This line passes thru the y axis at the center of circle.Radius and OW calculate easily
