A cylinder is a solid with two circular ends (see figure 1). A
cylinder can be formed by rotating a rectangle around one of its sides (see figure 2).
Click on the points on the sliders in figure one and drag them to change the figure. Click
on the blue point in figure 2 and drag it to see a cylinder form from a rectangle.
|V = πr2h||Volume|
|S = 2πr2 + 2πrh||Surface area||

One way to create a cylinder (in Geogebra anyways) is to rotate the cylinder about one of its sides.

Geometric Net of a Cylinder
A geometric net is a two dimensional shape that folds
into a three dimensional figure. Click here for a
geometric net of a cylinder
that you can print, decorate, cut out and tape together to make a cylinder.
