Which two-dimensional shape can be rotated about the y axis to create a cylinder which has a smaller diameter than height?

Rectangle

Step-by-step explanation:

If we rotate   a rectangle whose about Y -axis then a cylinder will be generated i.e. a vertical cylinder is generated whose volume is given by

where r= width of rectangle

h=length of rectangle

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
