Determine collision points/area

I'm making a basic dart game. I succeeded in implementing a basic throwing logic and also made the dart arrow stick to the board after colliding. I'm now struggling with determining where the arrow hit the board for calculating the points.

I made a basic "CircleMesh" for my board so that the arrow can only hit the board. Is there a way to specify areas in a mesh to detect were the arrow has hit the board?

(This shows the mesh I am using. I made just a simple extruded circle in blender. I don't know why unity is adding those support edges across the surface)
