you have 2 points, 1 is (0,0,0) 2 is (2,3,4) find out the distance between them, that's is the radius, isn't it?

Do I use the distance formula? Because there is no Z in the distance formula...

should i just ignore the Z? and just use distance?

the distance between the center and a point in the sphere is not the radius of the sphere?

why you have to worry about Z? your center is origin, what make you think that you cannot use it as a normal point?
