Question

23. Radii of two concentric circles are 26 and 24. A chord of the circle with
larger radius touches the circle with smaller radius. Find the length of the
chord.​

Answer 1

Answer:

To Find: Length of AB.

AB is a tangent to a smaller circle.

Then, OD perpendicular to AB.

By Pythagoras in ∆OAD,

OA2= OD2 + AD2

(26)2 = (24)2 + AD2

AD2=100

AD=√100

AD=10.

Similarly, By Pythagoras theorem...

AD=BD=10

So, AB=AD+BD

AB=10+10= 20 units
