According to a rule in geometry, the dimension of an object made up of n dimensions is n+1. For example a cube is 3d which is made up of squares which are 2d and a square is made up line segments which are 1d. So, as circle is made up of diameters which are 1d, it is 2d or second dimensional space. Hope you like it.
