You can put this solution on YOUR website! what is the equation of a circle with center (2,0) and radius 2 units? .
 Equation of a circle:
 (x-h)^2 + (y-k)^2 = r^2
 where
 (h,k) is the center
 r is the radius
 .
 Plug in given data into:
 (x-h)^2 + (y-k)^2 = r^2
 (x-2)^2 + (y-0)^2 = 2^2
 (x-2)^2 + y^2 = 4  (this is what they're looking for)
