Use cylindrical or spherical coordinates, whichever seems more appropriate. Find the volume V and centroid of the solid E that lies above the cone z = x2 +y2 and below the sphere x2 + y2 +z2 = 36 Find the volume V and centroid of the solid E that lies above the cone z = x2 + y2 and below the sphere x2 + y2 + z2 =36 V =
