The X axis is the horizontal(left-right) axis on a graph.
A dimension pertaining to the size of an object, generally within a horizontal axis.
pi/4 * minor axis (this is usually denoted as 2b) = pi/2*b. This would be the average width vertically.
Yes, the axis of the Earth passes through its centre.
The origin
The sun rotates on its axis and revolves around the galactic centre.
It is about 23.5 degrees
23.5 degrees from the perpendicular.
The axis just defines their rotation. It is relative to spin, so if a body does not spin, it has no axis. Kind of an imaginary line, like the equator. It is used for reference. Also an object that is not round and symmetrical and has a length and a width can also be referenced by these dimensions. The Longitudinal axis is usually an axis through the longest dimension of the body.
It is zero. Unless a width is specified, a cross-section is an infinitesimally thin slice across the axis of the object.It is zero. Unless a width is specified, a cross-section is an infinitesimally thin slice across the axis of the object.It is zero. Unless a width is specified, a cross-section is an infinitesimally thin slice across the axis of the object.It is zero. Unless a width is specified, a cross-section is an infinitesimally thin slice across the axis of the object.
Z represents the Z axis in any three dimensional graph or chart. It is often called "length", as in length, width, height. Width being the X axis, and Height being the Y axis.

In degrees it is the approximate tilt of the Earth's axis in 3 significant figures
