I'm confused by what you're saying exactly.
Looking back at the problem I see that I've left out; "The value of p + q is _____."
What would I do now?

anonymous · Answer

I apologize, what do I do though?
I'm still very confused.

the equation of a circle with radius r and center (h,k) is given by$$(x-p)^2+(y-q)^2=r^2$$so what are the coordinates of the center of the circle?

turingtest · Answer

*radius r and center (p,q)

anonymous · Answer

Ok, so this is what you do. The problem is asking for the value of $$p + q$$. So, obviously you must find the value. In this case, p is the value of the x coordinate of the center of the circle and q is the value of the y coordinate of the center of the circle. You can see from the attached image that the center of the circle is 1,3. So, p, q = 1,3. Thus p + q = 4.
