Radius of a circle is 34 $c m$ and the distance of the chord from the centre is $30 c m,$ find
the length of the chord.

Solution

$a = 30 c m$
$\Rightarrow r = 34 c m$
$\Rightarrow d = \sqrt{r^{2} - a^{2}}$
$= \sqrt{34^{2} - 30^{2}}$
$= \sqrt{256}$
$= 16 c m$
Length of chord $= 2 d = 32 c m .$
Hence, the answer is $32 c m .$
