public void Disk (double radius)

public double getRadius ()

public void setRadius (double radius)

public BBox getUnorientedBounds ()


Calculate disk surface area.
Since a disk has 2 sides :
2 * (Math.PI*radius*radius)
return  surface
public double getSurface ()


A Disk has no volume.
return  always 0
public double getVolume ()
