A circle.
For a right cone, it is a hyperbola which becomes and isosceles triangle when the section passes through the apex.
A rectangle.
The answer depends on the length AND the cross-section of the pipe. Just one of the two measures is not enough.
The equator and the tropics of Cancer and Capricorn

Any two-dimensional image of a cell is technically a cross section.
It will be one of:a triangle if where the cross section cuts the base is through two adjacent sides;an irregular quadrilateral if where the cross section cuts the base is through two opposite sides but not parallel to a side of the base; ora trapezium if where the is the cross section cuts the base is parallel to a side of the base.
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
A circle.
A cut along the transverse plane= transverse or cross section. *(If cut at an angle= oblique section).
Sorry- there is more than one. The originals were two piece that, when installed, had a roughly triangular cross section, flat on the bottom, but tapered in cross section as you moved up the barrel.
For a right cone, it is a hyperbola which becomes and isosceles triangle when the section passes through the apex.
It depends on the angle of the plane of the cross section. If it is parallel to the cube's face (or equivalently, two adjacent edges) the cross section will be a square congruent to the face. If the plane is parallel to just one edge (and so angled to a face), the cross section will be a rectangle which will have a constant width. Its length will increase, remain at a maximum level and then decrease. If neither, it will be a hexagon-triangle-hexagon-triangle-hexagon (triangles when passing through a vertex).
The number of faces in a prism is one face for each of the sides of its cross-section plus the two end faces. A quadrilateral prism has a quadrilateral as its cross-section. Therefore it has 4 + 2 = 6 faces.
The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
