You're on a roll — Step 1: Identify the given information from the problem and the diagram. The circle has center O. The radii are OP = OQ = OR = 5 cm. The lengths of the chords are PQ = 4 cm and QR = 9 cm. We need to calculate PQR. Step 2: Calculate POQ using the Cosine Rule in POQ. The sides of POQ are OP=5 cm, OQ=5 cm, and PQ=4 cm. The Cosine Rule states c^2 = a^2 + b^2 - 2ab C.
