Question

Two concentric circles are of radii 6.5cm
And 2.5cm.find the length of the chord of the larger circle which touches the smaller circle.

Answer 1

Answer:

Step-by-step explanation:

We know that the radius and tangent are perpendicular at their point of contact

In right triangle AOP

Since, the perpendicular drawn from the center bisects the chord.

PA = PB = 6 cm

Now, AB = AP + PB = 6 + 6 = 12 cm

Hence, the length of the chord of the larger circle is 12 cm.

Answer 2

Answer:

Step-by-step explanation:

PA = PB = 6 cm

Now, AB = AP + PB = 6 + 6 = 12 cm

Hence, the length of the chord of the larger circle is 12 cm.
