Answer 18

so

"perpendicular cross section of a cylinder " matches up with ________

Answer 19

circle?

Answer 20

yes, rectangle isn't an option when it should be

so circle is the next best thing

Answer 21

do i switch those 2 and there all correct?

Answer 22

"parallel cross section of a sphere"

that's either a circle or an ellipse, but circle is probably the better choice

Answer 23

the last two that you have are incorrect

Answer 24

but circle was the other one?

Answer 25

circle is definitely the answer for "perpendicular cross section of a cylinder"

because rectangle isn't an answer choice

Answer 26

can you tell me all the answers in order on here to make sure i have them right on mine.....basically checkin my answers

Answer 27

tell me what the last two are and I'll sum them all up for you in one post (assuming you get the next two right)

Answer 28

I have it in order like this now

triangle
circle
ellipse
cone
cylinder

Answer 29

the last two are mixed up and assuming you can only choose one answer only (and you have to choose them all), then the order is


triangle
circle
ellipse
cylinder
cone

Answer 30

oh I'm sorry about that

Answer 31

there must be a typo because "shape created when a rectangle is rotated about the y-axis " is definitely a cylinder
