["Sebastien Loriot (GeometryFactory)" <>]

Try something like:

typedef CGAL::Shape_detection_3::Sphere<Traits> Sphere_shape;
Sphere_shape sphere_shape = dynamic_cast<Sphere_shape*>(shape.get());

if(sphere_shape)
{
  Traits::Point_3 center = sphere_shape->center();
  Traits::FT radius = sphere_shape->radius();
}

Sebastien.
