How can create a dynamo file that can calculate area of a circle
In Design Script without building a new geometry:
Math.Pi()*Math.Pow(Circle.Radius(cir),2);
By nodes without building new geometry:

Or by design script with new geometry:
Surface.ByPatch(circle).Area;
By nodes with new geometry creation:
