Ellipse * * * * * At right angles to the length, it would be a circle. Along the length it would be a rectangle. Only a diagonal cross section would be an ellipse.
A rectangular prism has a rectangular cross section whereas a cylinder has a circular cross section
A cylinder has a circular cross section, a square prism has a square cross section.
A circle, ellipse, truncated ellipse or rectangle - depending on the inclination of the cross section relative to the cylinder.
The radius of a cylinder is half the thickness of its circular cross section.
Technically, no. A cylinder extends in both directions to infinity, but if you consider that it is limited in both directions, then, yes. Also, a cylinder does not necessarily have a round cross section and, if so, then no. Only a right circular cylinder will have a round cross section.
The shape of a transverse cross section of a cylinder is a circle.
A cut through a right circular cylinder that is perpendicular to its altitude yields a circular cross-section. A right circular cylinder that is cut on a plane not perpendicular to its altitude but also but also not parallel to its altitude will yield an ellipse whose minor axis is the diameter of the cylinder. Trivial cases of a set of parallel lines, a single line, or the empty set occur when the cut is parallel to the altitude, externally tangent to the cylinder, or does not intersect the cylinder, respectively.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.
A cylinder has a circular cross-section whereas a cuboid has a quadrilateral cross-section.
Ellipse * * * * * At right angles to the length, it would be a circle. Along the length it would be a rectangle. Only a diagonal cross section would be an ellipse.
A cylinder has a circular cross section, a rectangular prism has a rectangular cross section.
A rectangular prism has a rectangular cross section whereas a cylinder has a circular cross section
A cylinder has a circular cross section, a square prism has a square cross section.
A circle, ellipse, truncated ellipse or rectangle - depending on the inclination of the cross section relative to the cylinder.
The radius of a cylinder is half the thickness of its circular cross section.
The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.
