Question

draw a circle of diameter 6cm show centre chord ab radius OP chord XY and diameter LN​

Answer 1

Answer:

As AB is the chord. O is the centre of the circle. Since OP is the perpendicular drawn from O to AB as its distance, then OAP and OPB are both right angled triangles.

Now radius of the circle OA=OB=5cm

Using Pythagoras theorem, we have

=>OA

=25−9=16

=AP=

16

=4cm

Similarly, PB=4cm

Hence, AB=AP+PB=4+4=8cm

Answer 2

Answer:


The diameter is 6cm
Centre chord
