Question

PLEASE HELP! Will fan/medal for some help with this! Don't forget to look at my diagram below!!

If LM=6 and HI=36, calculate the length of diameter LO.

Answer 1

What are the r's?

Answer 2

r = radius of circle

Answer 3

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

Answer 4

Oh, okay so I'm confused..

Answer 5

apply pythagorean theorem in that right triangle and solve r :

\[\large r^2 = (r-6)^2 + 18^2\]

Answer 6

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