Answer 2

Ok this is the last one, and then thats it for this assignment

Answer 3

So these are the points on the plane

Answer 4

we're rotating it around the x-axis so like imagine it moving slowly around that line

you can cut out a triangle and rotate it and try to imagine it too that way

Answer 5

Kinda looks like pac man

Answer 6

Right?

Answer 7

well packman is like a sphere with a mouth but I kinda see what you're trying to say

Answer 28

So I just put its a cone

Answer 29

Answer 30

Doesn't it need more?

Answer 31

For the answer?

Just say: if it's rotated around the x-axis it would form a cone. Please use your imagination

and you can insert this drawing (if you can)

Answer 32

"Please use your imagination"?

Answer 33

Yeah ok I'll put that picture 😄

Answer 34

What if she asks me where I got it from?

Answer 35

your teacher will understand haha

I mean- it's all about spatial recognition

Answer 36

uh draw your own version and say you drew it duh

Answer 37

How do I draw it though...

Answer 38

open up microsoft paint? or draw it on a real paper and then take a picture and attach it
