Hi, Im unsure how to do this problem!

This problem uses cylindrical coordinates 2,r, 0 with r? = r² + y?.
Let H, m > 0. Consider a solid cone G defined by z < H and z > mr,
where m = cot(4.) and the angle between the lateral surface of the
cone and the central axis of the cone is o.. See Figure 1.

FIGURE 1. A cone of height H and central angle o..
Find the centroid (7, ỹ, z) of G.
Note that the cone becomes very narrow as o, → 0*, or equivalently,
as m → +o. Take your answer for the centroid above and compute
the limit
lim (7, ỹ, 2).
Finally, does your answer surprise you?
