From a drawing curve you can get its segments using the Segments property.  In this case it's likely there's just one segment but in any case you can just get the first segment.  The DrawingCurveSegment object has a Geometry property that in the case where the drawing curve does represent a circle will return a Circle2d object.  The Circle2d object supports Center and Radius properties.

 

Here's a blog post that illustrates a technique that's very useful in figuring out these kinds of things.  I just used this technique not to verify this so I could be sure about my response. http://modthemachine.typepad.com/my_weblog/2008/10/program-prototyping.html
