Answer 1

Plot the points

Answer 2

What do you get if you rotate it around the y-axis?

Answer 3

Answer 17

look at the images again until you see it or you need to review your shapes again

Answer 18

which shape?

Answer 19

the shape that gets formed by rotating a rectangle

Answer 20

its not a square?

Answer 21

`What 3-dimensional shape will be created when this shape is rotated about the y-axis?`

3-DIMENSIONAL

Answer 22

is a SQUARE a 3-DIMENSIONAL shape?!?!?!?!??

Answer 23

A triangle...

Answer 24

a triangle is not a 3-D shape

it is a two dimensional shape

These are 2 dimensional shapes

Answer 25

These are 3 dimensional shapes

Answer 26

3 dimensional shapes are shapes that you know, you can hold

They're 3D

2 dimensional shapes are shapes that are flat that you can draw

Answer 27

rombus

Answer 28

go learn your shapes and then tell me what shape this is

Answer 29

damn rude much

Answer 30

I can't help you more if you don't know what shape it is. Ask your parents, they probably know.

I understand not being able to visualize how it gets rotated around the y-axis and what shape it forms. But at this point, I've literally given you the answer. You just need to be able to recognize your shapes.
