When I read the volume compare theorem (first picture below), I think there should be a theorem about the boundary of ball, liking $$ vol (\partial B_r(p)) \le vol(\partial B_r(\tilde p)) $$ Further, the volume of sub-manifold should can be compared. For example, the second picture can be treated as special case (n=2) of volume compare of sub-manifold. I wonder if there is any research on this, and what is the corresponding paper?
