For n = 7 We can solve it only with circle of radius 3. However, we send the solution, which prints more than 3.

Please, correct the tests, or provide the reason this solution is wrong.

Have you READ the problem before submitting it? Statement is more than clear:

"At first you want to draw a circle and place all your bottles inside it so that *each* of the bottle bottoms *touches* the circle"

I fully agree with you, with 7 and 6  bottles the answer should be 3 and my program give me more than 3 for 7 bottles but the judge accept it, that's wrong or why not?

Oh yea! I also solved a circle packing problem at the beginning :)
But the problem is much more easier. This cost me a lot of contest time...

Yes! circle != disk )))
