\)
A solid in three-dimensional space. The solid is bounded below by an upward-opening cone with its vertex at the origin. The solid is bounded above by a horizontal plane. There are sliders for
\(x\) and
\(y\) that control the location of a vertical line segment from the bottom of the solid to the top of the solid over the point
\((x,y)\text{.}\)
