Chose a system of coordinates with the center at the left end of the semicircle,so that the Ox axis in its posotive part to comprise entire diameter.Therefore your equation for the curve will be slightly modified.

First find the domain of that function ([-3,3]). Then create an arbitrary partition of that domain. That is to say, select an arbitrary number of points in that domain and label them [itex]\{x_0, x_1,...x_n\}[/itex]. (x0 has to be -3 and xn has to be 3). In principle, the more points you chose, the better the approximation.

Then construct and evaluate the Riemann sum

[tex]\Sigma_{i=1}^{n} y(t_i)(x_{i}-x_{i-1})[/tex]

Where the ti are arbitrarily chosen points in the interval [itex][x_{i-1},x_{i}][/tex]
