Graph the integrand, and use area to evaluate the definite integral ( int_{-2}^{2} sqrt{4 - x^2} , dx ). The value of the definite integral ( int_{-2}^{2} sqrt{4 - x^2} , dx ), as determined by the area under the graph of the integral, is ( oxed{ } ). (Type an exact answer, using ( pi ) as needed.)
