Best ResponseYou've already chosen the best response.0Ok, x is 1/2 of 9 because it is the same distance from the center as the chord with the length of 9. Each chord is perpendicular.

Best ResponseYou've already chosen the best response.0Then you use Pythagorean theorum to find the radius which is y.

Best ResponseYou've already chosen the best response.0It is difficult to read but here we go. The two drawn chords are equal in length so both are 9. Therefore x= 4.5 Q13 y is a radius which can be found from the previous answer using Pythagoras again. r squared = 5 squared + 4.5 squared...you can do the rest I think :)
