Question

4. Find the length of the chord, if its distance from the centre of circle of radius 10 cm is 8 cm.
​

Answer 1

Answer:

Answer is 8 cm.

Step-by-step explanation:

Half the chord length = 6 cm. Radius of the circle = 10 cm. Distance of the midpoint of the chord from the centre of the circle = [10^2–6^2]^0.5 = [100–36]^0.5 = 64^0.5 = 8 cm.
