    1. The problem statement, all variables and given/known data

    here's a picture of the problem

    http://i39.tinypic.com/28u017m.jpg

    I am trying to workout the area of the section of the curve submerged in 2 m deep water.


    This is not a homework. I am studying for my exam.. so i am just doing a bunch of different problems.

    2. Relevant equations



    3. The attempt at a solution

    I know I have to calculate the angle of the curve submerged first in order to workout the area.

    I think you're making this more complicated than it really is. You can figure out the angle of the arc portion submerged in the water, then use basic geometry (i.e. sector area = angle (in rads) * .5 * radius^2), to get the area.
