Code: Select all

``````1 0 20 0 20 25
1 25 20 0 0 25
1 0 20 25 20 25
``````
All are the same cylinder with 20-diameter base and 25 height filled with 1 deep water, which volume is 314.159265

I found s=1.67 and the volume is 314.159272

Hi, my program outputs the wrong result 10 but that is because I consider it as an invalid testcase. A bottle should have rn>0. Anyway, my algebra program tells the volume for s=3.45 is 119.8352061. I found s=5.1 to yield a volume of 301.7440301. Maybe I make some fundamental error? Cu, Erik mm, I ...

Maybe we can discuss a simpler testcase

Input

Code: Select all

``````1 0 20 0 0 25
0 0 0 0 0 0
``````
My output is

Code: Select all

``````3.45
``````
This is a cone bottle with a 20-diameter circular base .

We use the same idea calculating the cross section. In fact, I directly calculate the volume of the cross section instead of integration. V= fan-based pyramid - triangular-based pyramid = (1/3)*h*[r*r*acos(x/r)] - (1/3)*h*x*[sqrt(r*r-x*x)] But I'm not sure whether the calculation of triangular-based...

### To Erik

To Erik: I also got WA. While compared to your testcase, all are different except the first and the last testcase. The following outputs are generated by my WA prog. 0.00 2.43 3.92 5.22 6.42 7.56 8.62 9.65 10.67 11.70 12.79 13.86 14.81 15.66 16.40 17.05 17.60 18.06 18.43 18.71 18.90 19.05 19.22 19.4...
