What is the vertical cross-section of a solid cylindrical pipe shown in the figure?
- A. An ellipse
- B. A circle
- C. A cylinder
- D. A rectangle
Step-by-step solution
A vertical cross-section of a solid cylindrical pipe, taken parallel to its axis (i.e., a plane containing the axis), yields a rectangular cross-section. This is because the intersection of a vertical plane with a right circular cylinder produces a rectangle. The other options are incorrect: an ellipse results from an oblique cut, a circle from a horizontal cut, and a cylinder is a 3D object, not a cross-section.
