Question

the radius of circle with Centre P is 25 CM the length of a chord a b of the same circle is 48 cm find the distance of chord from the centre of the circle​

Answer 1

hi..

let AB be chord of circle...(fig in attachment)

In AOP

<OPA= 90° (angle at point of contact)

so in AOP,
▪OA = 25 cm
▪OP= x cm
▪AP= 24cm

${ OA}^{2} = {OP}^{2} + {AP}^{2}$
${25}^{2} = {x}^{2} + {24}^{2}$
$625 = {x}^{2} + 576$
${x}^{2} = 625 - 576$
$x = \sqrt{49}$
$x = 7cm(chord \: distance)$
