Hi i know how to do these problems but its calculating the weight of the fluid, which you have to do to minus it from the vertical force.

But in the solutions to the problem is say that the volume is R^2 - Pie *(R^2)/4 *1

The only thing i want to know is why is that the volume because ive never seen anything like it and if it is correct is it in all the problems so i can just remeber it.

Cheers
