Question: Torus: Graph, volume, surface area

I am trying to graph a torus using maple.

z= 1 - (r - 5)

Could someone please help. I think I need to use implicitplot3d but need help setting it up.

I also want to set up an integral that will allow me to find the volume and surface area of the torus. Any help appreciated. I do not know maple that well at all by the way.
