Hi I was just curious if this method of solving whether or not two spheres intersect is a viable method that will give me the correct answer. Say if I am given the two equations of the sphere's is it viable to:

Thanks in advance!

- Find the centre and radius of each sphere.
- Find the magnitude of the distance of the line between the sphere's centres
- If (magnitude distance of line) > radius they do not intersect, if (magnitude distance of the line) ≤ radius they do intersect.

Thanks in advance!
