A chord distance 2 cm from the centre of a circle is 8m long. Calculate the length of a chord of the same circle which is 6cm distance from the centre.

Answer 1

The semi-chord has length 400cm, and so forms a right triangle with hypotenuse √160004 cm, which is the radius of the circle.

So, a chord 6 cm from the center will be 2√(160004-36) = 2√159968 = 8√9998

I suspect a typo somewhere ...
