khmm. I don't know, what kind of cheat did you use, but it was very useful help. After some manipulations with precision, finally AC! Thank you

Why test2 has answer 36? it seems that correct answer is 25.

Yes, answer is correct.
Center - 3.83333 3.83333
radius - 4.00694
x_min ~ -0.173605 < 0
y_min ~-0.173605 < 0
S = 36
