I was wondering whether anyone experienced with GeoGebra could create an applet that does this: https://www.geogebra.org/m/jzsxxnhq 
but rearranges a cylinder into a cuboid rather than a circle into a rectangle. I was also wondering whether this applet https://www.geogebra.org/m/yzGzrUxs could be modified or recreated so someone can change the height of the cone.
