2√7

Step-by-step explanation:

Mathematically, the equation of a circle can be represented by;

(x-h) ^2 + (y-k) ^2 = r^2

where (h, k) = center and r = radius

Applying this to the question, we can see that the length of the radius of the circle is √7

The diameter is always twice the radius

Thus, the diameter KL = 2 * √7 = 2√7
