Getting a "Constructor is undefined" error in my Billiards game

I'm working on a project for one of the classes at my university and I'm getting an error that the constructor for the Ball class is undefined. I thought the way I set it up was correct and I'm not exactly sure what I'm doing wrong with the constructor. Your advice on fixing it is appreciated. :)
