'draw'-Gnuplot interface:
object cylindrical

Once you have opened a Maxima session, load package draw:

load("draw") $

To read the documentation on object cylindrical, write the following sentence:

describe(cylindrical) $

Three geometric objects defined in cylindrical coordinates:

draw3d(
  surface_hide      = true,
  axis_3d           = false,
  proportional_axes = xyz,

  color             = blue,
  cylindrical(z,z,-2,2,a,0,2*%pi), /*cone*/

  color            = brown,
  cylindrical(3,z,-2,2,az,0,%pi),  /*cylinder*/

  color            = green,
  cylindrical(sqrt(25-z^2),z,-5,5,a,0,%pi) /*sphere*/ )$
