Answer 1

lol you're using internet explorer

Answer 2

it has to be a square

Answer 3

Imagine that thing rotated across the y-axis. It will be a cylinder

Answer 4

Since in a cylinder, the top circle is equal to the bottom circle, it has to be a rectangle. The points can be anything you want

Answer 5

For example, let's say (0,0) , (5,0) , (0, 10), and (5,10)

Answer 6

There cannot be space between the rectangle and the y-axis.
If there was space between them, then it would not make a cylinder. It would make a "hoop"

Answer 7

I get so confused when it comes to rotations, it was my worst section

Answer 8

I know, this is really hard. The only reason I know this is because of calculus. I wouldn't be able to solve it but some people expect you to.

Answer 9

Do you understand the answer?
