Question

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

Answer 1

A rectangle rotating about the y-axis will generate a cylinder after a rotation of 360°

Answer 2

Answer:Rectangle

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

`V=\pi r^2h`

where r= width of rectangle

h=length of rectangle
