Question

Find the length of a chord of a circle radius (✓x2+y2)cm whose distance from the centre of the circle is y cm​

Answer 1

Answer:

A chord intersects the circumference at two and only two points.

Now the diameter of a circle is a chord, since it intersects the circumference at two and only two points.

The lengths of all the paralles of the diameter are less than the length of the diameter.

So, diameter is the greatest chord.

Here radius =8

2

cm

⇒ diameter =2×8

cm =16
