CYLINDERS |
||
 |
||
 |
 |
When
a plane curve is displaced up and down following the direction of a
straight line perpendicular to the plane… we get cylinders. If the
curve is a circumference, we get a circular cylinder, also generated if
a straight line is rotated around another parallel straight line.

 |
What
are the level curves of a right-angled cylinder? |
