If the rotational curve (orbital speed versus distance from center) of a spherically symmetric object is flat, what is implied about the mass density? It decreases with distance from center. It remains zero far from the center because the distribution is essentially a point mass. It increases with distance from center. It remains constant at all distance from center.
