Question

Answer 1

Hello,

If a solid ring is a TOR (tore in french , a room air   )

then answer D

Answer 2

Answer: A solid ring

Step-by-step explanation:

From the given diagram, if the circle revolves about the vertical dashed line.

We can see that there is some distance between the circle and the vertical line, which is represented by horizontal dashed line.

So, when it revolves about the vertical dashed line, it will form a torus (donut shape).

A torus is nothing but the solid ring .

• A torus is a surface of revolution generated by revolving a circle in three-dimensional space about an axis with the circle such that the axis of revolution does not touch the circle.
