- C6 cm
- D10 cm
Step-by-Step Solution
The chord is tangent to the inner circle, so the radius (3 cm) meets it at right angles at its midpoint. Half-chord = √ √16 = 4 cm, so the full chord = 8 cm.
Answer: A) 8 cm
Two concentric circles have radii 5 cm and 3 cm. The length of the chord of the larger circle that touches the smaller circle is:
