Answer 2

Answer:

Step-by-step explanation:

The length of chord is 6 cm.

Step-by-step explanation:

Since we have given that

Radius of small circle = 4 cm

Radius of large circle = 5 cm

So, we need to find the length of each chord of one circle which is tangent to the other circle.

Since it forms a right angle triangle.

So, it becomes,

So, Length of chord is given by

Hence, the length of chord is 6 cm.
