If horizontal, a circle. If vertical, a semi-circle.
The vertical cross sections are trapezia or triangles. The horizontal cross sections are rectangles which are mathematically similar to the base.
It is a rectangle which is similar to the base.

Circle
They are all circles. The vertical and horizontal have the same radius as the ball while the angled cross section has a smaller radius.
If horizontal, a circle. If vertical, a semi-circle.
The vertical cross sections are trapezia or triangles. The horizontal cross sections are rectangles which are mathematically similar to the base.
The vertical cross section of a right vertical cone is a triangle if that cross section is taken from the vertex. Any other vertical cross section will reveal a hyperbola (with endpoints on the base of the cone). A link can be found below.

Jesus was crucified on a cross. The main section was vertical and the cross bar was horizontal and a few feet below the top of the main section as we are told that a sign was placed on the cross above His head. We do not know what kind of wood the cross was made of.

If the cylinder is standing on its flat face, the horizontal cross section is a circle. Otherwise, it is a line or a rectangle.
