The site listed below shows different images of the same subject using different lenses. This will give you a visual representation of what, or how much of an area different lenes will cover.
Scroll down to about 1/3 of the page, the area covered by a 3.6mm lens is represented in the second frame,a 22mm focal length with a 94* angel.
