Morning black — let's get this done. Question 18: Two circles with centres O and Q and radii 8cm intersect at points A and B. The distance between O and Q is 12cm. The line AB meets OQ at X. a) the length of the chord AB. Step 1: Draw a diagram and identify the given lengths. Let r be the radius of each circle, so OA = OB = QA = QB = 8 cm. The distance between the centers is OQ = 12 cm. The line segment AB is the common chord. The line connecting the centers OQ is the perpendicular bisector of the common chord AB. This means $
