Answer 3

i would think you need to graph a shape of half circle to that when rotated makes top of the cone like shape

Answer 4

I have know idea what to do at all

Answer 5

anyone?

Answer 10

I saw that before but what would I write as my answer?

Answer 11

U can plot (0,5) and that could be the vertex of the cone
Plot another point on the x-axis, lets say (3,0) and call it B

Answer 12

ok got it

Answer 13

Connect AB and rotate it around the y-axis, which actually means you're just rotating B because your point A is the vertex which will be a fixed point

Answer 14

If you rotate, you would find another point you can graph call C which is (-3,0)

And your cone would have a radius of 3

Answer 15

is that it? if so what would I put as my final answer?

Answer 16

I think that's it. And you could write something based on that^
