    take \[x=rcos \phi \cos \theta, y=r \cos \phi \sin \theta, z=rcos \theta\]

    and you plug those into the integral but what are the bounds

    then \[f _{avg}=3/(4\pi)\int\limits_{r=0}^{1}\int\limits_{\theta=0}^{\pi}\int\limits_{\phi=0}^{2\pi}r ^{3}\sin ^{2}\theta \cos \theta \sin \phi \cos \phi drd \theta d \phi\] probably this will give you 0
