Answer:
8 cm
Step-by-step explanation:
- Mark the center an O.
- Mark the point of contact of the chord to the smaller circle as A
- Mark the Point of contact of the chord to the bigger circle a B
- Join A , B , O.
- OA = 3cm
- OB = 5cm
By applying pythagoras theorem.
AB = 4 cm
Thus the length of chord is 8 cm
