Let F be the solid sphere 0 lt; x* + y? + z?

Please answer the attached question. It involves calc 3. Thanks

Let F be the solid sphere 0 < x* + y? + z? $ 1 of radius 1 centered on the origin and let /, be the portion of F that lies in the first octant. Assume that f(x, y, z) is a continuous function that issymmetric with respect to reflections through the coordinate planes. That is:f(-x, y, z) = f(x, y, z), f(x, -y, z) = f(x, y, z), f(x, y, -z) = f(x, y, z).If1, "(x, Y, 2) dv = 317, find the value of((x, Y. 2) av.
