What I thought of doing is to transform the axis in such a
way that the z axis becomes perpendicular to the new axis
and we are able to use the plane so obtained to draw the
circle.

That will work, but it is unnecessary. Just realize that
all 3 points must be the same distance from the center.
There will only be one point that fits this criteria. The
3 known points along with the 3 dimensions will give you 3
equations on the 3 variables (x,y,z value of the center).
Once you have have the center, determining the radius will
be easy.

Good luck!

But I find the problem in plotting it.In 3 D matlab plots a
sphere given radius and center.How to get a circle??
