Answer: C) 6"
Explanation:
Focus on the fourth circle only.
Radius LD is 3 inches, so the diameter is 2*(radius) = 2*3 = 6 inches which is segment LH. The diameter has endpoints on the circle and the segment goes through the center of the circle.
Alternatively, you can say LD = DH are both radii, so DH = 3 and LH = LD+DH = 3+3 = 6.
Either way, LH = 6.
