Question

What are the coordinates of the center and the radius of the circle given by the eqation?
 (x-1)^2 + (y-5)^2=16            Equation of a circle=(x-h)^2=(y-k)^2=r^2     Center: (h,k)

campbell_st · Answer

ok the general form is 

$$(x-h)^2  + (y - k)^2 = r^2$$

any ideas of the values for h and k when you compare it to your equation?

campbell_st · Answer

and the 2nd part... the radius... in your question r^2 = 16

what is the value for r?
