The diameter of a circle is 10 cm. If the distance of a chord from the centre of the circle be 4 cm, then the length of the chord is
Answer: (1) 6 cm
Solution:-AP = sqrt, (5^2 – 4^2) = sqrt.(25 – 16) = sqrt.9AP = 3 cm
Then, the length of the chord AB = 2 x 3 = 6 cm
Hence, the correct answer is option (1) 6 cm.
