Answer 2

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,

$H^2=B^2+p^2\\\\5^2=4^2+B^2\\\\25-16=b^2\\\\B^2=9\\\\B=3$

So, Length of chord is given by

$2B=2\times 3=6\ cm$

Hence, the length of chord is 6 cm.
