Step 1: Determine the length of AD. D is the midpoint of the chord AB. Given AB = 300 mm. AD = (AB)/(2) = (300)/(2) = 150 mm Step 2: Identify the relationship between the center, radius, and given lengths. Let O be the center of the circle and r be its radius. Since D is the midpoint of chord AB and DC AB, the line segment DC passes through the center O. C is a point on the circle, so OC is a radius, OC = r. The distance from the center O to the chord AB is OD. From the diagram, C
