  In this paper, we study the Hausdorff dimension of the Floyd and Bowditch
boundaries of a relatively hyperbolic group, and show that for the Floyd metric
and shortcut metrics respectively, they are are both equal to a constant times
the growth rate of the group.
  In the proof, we study a special class of conical points called uniformly
conical points and establish that, in both boundaries, there exists a sequence
of Alhfors regular sets with dimension tending to the Hausdorff dimension and
these sets consist of uniformly conical points.
