Best ResponseYou've already chosen the best response.0\(r^2\) is 64 but you are asked for the radius, which is \(r\) what number would you square to get 64?

Best ResponseYou've already chosen the best response.0so that's the answer, right? 8?

Best ResponseYou've already chosen the best response.0\(64=8^2\) so \(r=8\) yw

Best ResponseYou've already chosen the best response.0Wait guys, I have another question. segment PR has an endpoint at (25, 5) and a midpoint of (18, 1). What is the value of the xcoordinate of the other endpoint?
