calculate the integral of f(x,y) = xy over the area that is defined from the equations below

x^2+y^2 <= 1, x>=0, y>=1/2

3. The attempt at a solution

first i tried to figure out the graph

so i want to find the value from the black surface and z = xy right?

so i say that it is equals to

what am i doing wrong?
