Homework Help: Spheres, Locus (in space aka 3d)

Posted by Billy on Monday, May 14, 2012 at 5:43pm.

1) A "small circle" is a circle on a sphere that is NOT a "great circle".
What is the locus of the centers of ALL small circles of a sphere having radius 1/2 that of the sphere?

I think the answer is a plane?
But I'm not sure.
Please help me!
