https://codeforces.net/contest/629/submission/46721512 This is the link to my solution to 629D. I am getting WA on 59th testcase. The error is of the order of exp(-5) but I am not able to figure out the reason why I am getting that error. I have set the precision to 12. Many other solutions with same precision have passed. Is there something else I am missing?

Try storing pi as long double
long double pi = acosl(-1)Your method will cast your pi value into double when not adding suffix
lto the number.Still gives the same answer. Thanks anyways
This is actually not a precision error. The answer is basically an integer multiplied by PI, so you can never get a precision error if you find the integer part correctly.
I haven't read tried to understand your solution but there might be a problem with
position[r*r*h]=i;, since there can be multiple values of r*r*h.
