If the circle in the diagram revolves about the vertical dashed line, which type of geometrical shape will it generate?

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 .

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
