Use spherical coordinates. (a) Write an integral that can be used to find the volume of the solid that lies above the cone go = g and below the sphere p = 12 cos(qo). in A '12 cos(ga) _ / [ l ( p231n(9) )dp 0'? d9 . O . 0 . B x A = -144 \"K s = 1350 X Find the volume. 270% ./ (b) Find the moments about the three coordinate planes of the solid found in part (a). Mn]: 0 x M.= 0 J M3,: 6J3 x Find the centroid of the solid. (;,;,2)=( 0,0,63 J )
