Image circle at diff. aperture, focus distance difference, etc?

There has been some talk about using 35mm lens on 33x44 sensor camera.

So, without getting into the technical stuffs.  Here are my few questions:

1> Image Circle is bigger when focus point is closer?

2> Image Circle is bigger when aperture is smaller?

3> Image Circle is bigger on telephoto lens than Ultra wide angle?

Thanks
