Flash question: Characterize:  $\sqrt{\left(x-h\right)^2+\left(y-k\right)^2}=r$  

• This equation shows the radius is the distance between two points.

• This equation is difficult.

• I give up.

• This equation can be view as something of interest, however since I don't read much I will select this answer as it looks the longest.
