When n > 6 the cases are wrong. Try to do it without placing a circle in the center.

Why is this happening ... according to websites that can be trusted, the answers are different -

In other words, these are not the optimal values,
i.e. for test 8
the value using the simpler (and not accurate formula) - 3.6131259 is accepted,
when the optimal value is less than that - 3.3047648

When n > 5 I guess, you can place one or more circles to free place within polygon?
I assume that answer for 5 and 6 is same

ive googled that the answer for all n except 1 is 1 + 1/sin(PI/n), can smb explane me why?

for n:=1 to 50 do :
1

please write the 5 test. I got wrong answer

What is the solution for n = 10?

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.

"Circle" generally means «окружность», not «круг». English term for «круг» is actually "disk"/"disc". Don't let Google Translate confuse you on this matter!

I cant find my mistake please help me what is test 5.
