AP Calculus related rates problem?

The volume V or a cone (V = 1/3 ð r² h) is increasing at a rate of 28ð cubic units per second. At the instant when the radius r of the cone is 3 units, its volume is 12ð cubic units and the radius is increasing at 0.5 unit per second.

c)At the instant when the radius of the cone is 3 units, what is the instantaneous rate of change of the area of its base with respect to its height h?

my teacher showed my how to get the answer but i dont understand why..can someone show the steps with explanation PLEASE?

..by the way the answer is 3pi/8
