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.

The cross-section of a cuboid is unified in the shape of a square or a rectangle.

A circular cross-section.

A cross-section refers to the end of a prism, cones are not prisms. A shape like a cylinder is a prism. Hexagonal prisms have hexagonal cross-sections, and pentagonal prisms have pentagonal cross-sections. It's that simple.But for the sake of what the question COULD mean, I'll try and help.The easiest way to find the shape of a part of a three-dimensional object is to tear it apart (literally) and look at its net. The curved surface area of the cone looks like a rectangle when the cone is split open.Here are some formulas for the fun of things:Volume of cone = 1/3πr2hSurface area of cone =πrs +πr2π = Circumference (Perimeter of the circle) / Diameter (Length from one end of the circumference to the other end passing through the centre)r = Radius (Half the diameter)s = Side length (Up the side of the cone to the top)

By definition, the circular cross-section of a cone changes linearly in width as you go along its axis. By definition, the cross-section of a prism is constant along its axis. So, by definition, a cone prism is an impossible shape.

The strongest shape in nature is the triangle. A traffic cone has a cross section of a triangle. This would give it strength especially when knocked into by the traffic.

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.

The cross section will be a triangle with base 2 feet and a vertical height of 9 feet.

A point, a straight line, a circle, an ellipse, a parabola and half a hyperbola.

Circle

The answer depends on the angle at which the axis of the cone intersects the cross-sections.

If it a right cone then it is a circle, otherwise an ellipse.

A "cross section" is what occurs when you "slice" a given shape in a particular way, so that you can visualise the shape in two parts (with 2 new faces). The cross section is the surface (face) of the side which you have just sliced. E.g If you imagine a cone, with the circular base resting on a surface. You now slice the cone horizontally, so that you now have a very small cone (on top), and a "truncated cone" (2 circular faces, top one slightly smaller, with sloping sides joining them) below. The "cross section" is the top face of the truncated cone, and the lower face of the small cone (both cross sections are the same!). i.e they are the new "sides" that you have created. These new "faces" are both circular, so if you were to find the area you would use the formula pi*radius^squared = area.
