    Do I just assume that 9 is the total length so x would be half of 9?

    12 and 13 finding x and y. For x do I just assume that it is half of 9?

    Ok, 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.

    Then you use Pythagorean theorum to find the radius which is y.

    It 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 :)
