Homework Equations
F=A*p
The Attempt at a Solution
For A I believe the solution should be 1000*9.81*2d*d^2 = 2183404N
and B should be 1000*9.81*2.5*d*d^2 = 2729255.8N
but these both seem to be wrong. Based on other solutions to the same question found around the internet, this should be the solution as well, but apparently it is not. Unless atmospheric pressure is supposed to be factored in, which I doubt it is, I have no idea why this is wrong.
