h and k are just arbitrary letters chosen to represent values in a standard circle equation, Now they are a convention, so everyone usually uses those letters.
Circle equation in standard from is: (x-h)^2 + (y-k)^2 = r^2
h and k stand for x and y coordinates of a circle's center, r is radius.

 

2,-2(center)

5.92(radius)
