a surface tends to be 3 dimensional; therefore the given point would have to have 3 components as well in order to reside in the same metric space.

ideally tho, you would find an equation to the normal plane of the surface that contains the given point and measure your distances within that plane of reference

well in this case I am assuming that it means to the point x=0,y=0 where z is arbitrary because it is a cylinder.

otherwise its not a surface, and is meant to be a curve: http://www.wolframalpha.com/input/?i=x%5E2%E2%88%92xy%2By%5E2%3D3

well in 3d it is as surface. I get a cylinder on grapher. Not any close to answering the question though :(.
