Traffic Cone (AR Modeling Challenge)
This traffic cone (in the screencast below) has a square base.
Find a traffic cone (similar to the one in this screencast) and build it within GeoGebra Augmented Reality or in GeoGebra's 3D Graphing Calculator.
When doing so, be sure the circular base of the cone aligns perfectly along the circle along the square base.
Have fun with this!
