Best ResponseYou've already chosen the best response.3Center would be the midpoint between those two points, and the radius would be the distance between them divided by 2

Best ResponseYou've already chosen the best response.0So I do the midpoint formula using the two points to find the center?

Best ResponseYou've already chosen the best response.0Wait, I think I know why..

Best ResponseYou've already chosen the best response.0I still didn't get it. Isn't it d=\[\sqrt{(x2x1)^{2}+(y2y1)^{2}}\]

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

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

Best ResponseYou've already chosen the best response.0Oh, I got it now. I just added wrong. Thanks!
