Question

Radius of the circle is 12cm there are
two chords of length 10 cm
10 cm each what
will be the distance of these chords from
the centre OF the circle​

Answer 1

Answer:

the answer is 6cm

Step-by-step explanation:

Length of the chord AB=16cm and radius(r)=10cm.

To find:- OM

Construction: Draw a perpendicular OM from centre O such that it bisects the chord AB

Proof: In right angled ΔOMB

OB

+64

⇒OM

=100−64

⇒OM

=36

⇒OM=

36

⇒OM=6cm

∴ Hence, the distance of the chord from the centre of the circle is 6cm.
