python - Creating a circle with radius in metres

I am using shapely and python.

How should I go about creating a circle using shapely whose radius is in meters?

If i use

sampleCircle = Point(1,1).buffer(1)
print sampleCircle.area

This returns an area of 3.13654849055. How do I interpret the unit of this area? I read that this can be interpreted in square degrees but seek a little more explanation.

Also, how do i create a circle with a specified radius (in meters) around a point (defined using lat,long)?

The closest article I found was this [http://comments.gmane.org/gmane.comp.python.gis/1582] but it lacks any concrete solution
