Question

the diagram shows a cylindrical shell and its axis of rotation. if a plane passes through the axis of rotation, which cross - section will be formed? shape 1 shape 2 shape 3 shape 4

Explanation:

Step1: Understand cylindrical shell

A cylindrical shell has a circular - cross section perpendicular to its axis of rotation. When a plane passes through the axis of rotation of a cylindrical shell, it cuts the shell along its length.

Step2: Visualize the cross - section

The resulting cross - section will be a rectangle. The height of the rectangle is the height of the cylindrical shell, and the length of the rectangle is related to the circumference of the circular cross - section of the shell.

Answer:

shape 2
