## Simple question of solids...

Maple
Hello there, Would appreciate if someone could illustrate the procedure to obtain, using the plot3d command, simply the solid bound by the given set of graphs. In other words, all superfluous areas are substracted. For example, for the cone z=sqrt(x^2 + y^2) & planes z=2 & z=4, I'd like to see just the solid bound by the planes and not what appears when the following commands are executed: a:=implicitplot3d(z = sqrt(x^2+y^2), x = -5 .. 5, y = -5 .. 5, z = -5 .. 5); b:=implicitplot3d(z = 2, x = -5 .. 5, y = -5 .. 5, z = -5 .. 5);
