\[(xh)^2+(yk)^2=r^2\] is the equation of a circle with radius \(r\) and center \((h,k)\)

in your case \(r^2=64\) what is \(r\) ?

And how do I translate that into the real equation?

I actuall don't know what R is. :/

\[(xh)^2+(yk)^2=r^2\\(x5)^2+(y+2)^2=64\] look almost identical

okay, so it's 64. Right?

\(r^2\) is 64 but you are asked for the radius, which is \(r\) what number would you square to get 64?

so that's the answer, right? 8?

\(64=8^2\) so \(r=8\) yw

Wait 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?
