help :(((((((

Answer 4

Hint: think of a revolving door. The door itself is a rectangle. When it revolves, it sweeps out a space that is a cylinder

Answer 5

@jim_thompson5910 thank you for helping, may you walk me through this question?

Answer 6

simply plot any rectangle on the xy axis that has the point (0,3) on it

if you spun the rectangle around the y axis, you would get a cylinder. And this would mimic a revolving door

imagine each pane of glass as one rectangular piece

Answer 8

@jim_thompson5910 alright i did

Answer 9

so all you have to do really is add more points that define this rectangle and then explain how to use this rectangle to create a cylinder

Answer 10

@jim_thompson5910 may you illustrate?

Answer 11

what do you mean?

Answer 12

How would i explain the answer? @jim_thompson5910

Answer 13

Answer 14

yes @jim_thompson5910

Answer 15

you're just explaining that to the teacher really

Answer 16

you are going to explain to him/her that taking a rectangle, spinning it around, will create a 3D cylinder
