Question

A point A is graphed at (0, 3). Complete the coordinates of a shape that can be rotated about the y-axis to create a cylinder

Answer 1

Below is the answer:

Any rectangle with a side against y-axis can be rotated about y-axis to create a cylinder.

The other 3 coordinates will be (a, 3), (a, b), (0, b)

This will be a cylinder of radius a and height |3−b|
