What are the r's?

ganeshie8 (ganeshie8):

r = radius of circle

ganeshie8 (ganeshie8):

since LM passes through the center and perpendicular to chord HI, LM bisects HI.

Oh, okay so I'm confused..

ganeshie8 (ganeshie8):

apply pythagorean theorem in that right triangle and solve r : \[\large r^2 = (r-6)^2 + 18^2\]

i don't think K is center ...Q is the center, right ?
