Cone and Cylinder AR Modeling Challenge

In the screencast below, both the cylinder and cone have equal radii and equal heights. The height of each is double the radius. Their circular bases are tangent to each other. How can we construct this 3d image in GeoGebra 3D Graphing Calculator on your device? Try to do so, and then project what you create in Augmented Reality. If you're up for it, you can find such solids or create them from cardstock and put them to the "AR TEST" as shown in the screencast below. How well do the virtual images place when superimposed on top of the real world objects?
