Center would be the midpoint between those two points, and the radius would be the distance between them divided by 2

So I do the midpoint formula using the two points to find the center?

Graph paper would work great for this problem

Yep, use the midpoint formula

I know its suppose to be 5, but I didn't get it.

Wait, I think I know why..

I still didn't get it. Isn't it d=\[\sqrt{(x2x1)^{2}+(y2y1)^{2}}\]

CalebBeaversBest ResponseYou've already chosen the best response.3
Yeah thats it. Plug in your coordinates \[D=\sqrt{(1+9)^2+(0+6)^2}\]

CalebBeaversBest ResponseYou've already chosen the best response.3
youll get d=sqrt{100} d=10 but remember thats the diameter, radius is diameter divided by 2. 10/2=5

Oh, I got it now. I just added wrong. Thanks!
