WebAnalyzing the radius first: you have an image that is 12 circles wide and 8 circles tall, which gives you a diameter of roughly width/12 for each circle, or a radius of (width/12)/2. The constraints that you have used allowed the algorithm to detect circles way bigger or smaller than necessary, therefore you should use a parameterization that is better fit for your image.
