Question

the radius of a circle with Centre P is 25 the length of a chord of a circle is 48 centimetre find the distance of a chord from the centre of a circle

Answer 1

Answer:7

Step-by-step explanation:Let CD be the chord and PD the radius

Cons:Draw OP perpendicular bisector to CD

Then OD = OC =48/2=24. ( we know perpendiculars drawn from the centre to the chord bisects the chord)

In ∆OPD

ANGLE O =90°

Therefore using Pythagoras theorem

OP^2 +OD^2 = PD^2

OP^2= 25^2 -24^2

= 625-576

= 49

OP=√49

OP = 7

Hope this may help you!!
