GeoGebra
has tools that can be used to draw cylinders in 3D space and compute their volumes:
If you know the radius and height, use Item 4.
If you know the center of the base, center of the top, and the radius, use Item 4.

. Example 1
Draw a cylinder in GeoGebra
with a radius of 3 and a height of 4.
Follow Item 4 for solving this exercise. Draw a circle with the given radius in Graphics View
. Then use
Cylinder(Circle, Height)
where you type in the name of the circle and the given height.
