Question

the radius of the circle with center P is 25 cm the length of a chord of a circle is 48cn find the distanc of the chord form the center P of the circle

Answer 1

Answer:

7cm

Step-by-step explanation:

Let the centre be P.

Let the chord be AB.

Let the chord meet AB at O.

∠POB=90° because line drawn from centre to the chord of  circle makes right angles with it. (theorem)

OB=AO=48/2=24cm

Join BP.

Using pythagoras theorem,

h²=p²+b²

25²=24²+OP²

625=576+OP²

OB²=49

OB=7cm
