Note that for both the sphere and the cone, there are no restrictions on , so the solid is therefore described byB ={(,, )|05,02,0 tan1(2)}.Remembering thatz = cos()anddV =2 sin() d d d,we rewrite the triple integral in spherical coordinates.Bf(x, y, z) dV=Bz dV==2=0 = tan1(2) =0=5=0p5cos() sin() d d d==2=0 = tan1(2) =0p64cos() sin()=5=0d d==2=0 = tan1(2) =0cos() sin() d d
