I have spend more than an hour, but... (+)

My solution is correct, but I still cannot solve this problem fast. Maybe the time limit should be increased? I doubt it is an optimization problem.

AC! The time limit may be beaten. Yes-s-s... ;) (-)

It's not an optimization problem, it's just an easy math problem:

AC in 0.001 ;)

Re: it's just an easy math problem

Is your solution O(1)?

If so I want to know it ;) As for me I cannot deduce the formula (-)

We have 3 cones. 1 with round bottom and 2 with parabolic bottom.

Wow! It is SUPER solution! (+)

I spend whole day for finding formula by treble intagrals, but all what I got was cumbersome formulas, and when i read you hint I solved it immediately :-)... I was SO happy :-)

THANK YOU VERY MUCH!!!

Re: Wow! It is SUPER solution! (+)

Really a good hint. I was really surprised when found that volumes of both cones with parabollic bottoms are EQUAL =)

Better to use Simpson numeric integration by height with respect to area of horizontal segment of circle of constant width.
