Question

If a chord 16 cm long is 6 cm away from the center of the circle. How long is a chord 5 cm away from the center?

Answer 1

Answer: Chord =16 cm

.. . .. . ... =16/2=8cm

........ .distance between chord and center is 6cm

Radius of circle =√8^2+6^2

.... ....... =√100

.. .. =10cm

Now,

Length of chord =5cm

5/2cm=2.5cm

Radius of circle=10cm

Distance between chord and center=√10^2-2.5^2

=√93.75

=9.65cm ans
