Answer:
15 meters
Step-by-step explanation:
The diagram of the problem is attached below in the first image.
Chords KM and LN (which is the diameter) intersect at X.
Theorem: If the diameter is perpendicular to a chord, it bisects the chord.
Therefore:
LN divides KM into equal parts of 6 meters,
Applying the theorem of intersecting chords:
KX*XM = LX*XN
6*6=3*XN
3*XN=36
XN=12
Next, we find the length of the diameter LN
LN=LX+XN
=3+12
=15 meters
The diameter of the completed circle is 15 meters.
