Answer:

16cm

Step-by-step explanation:

given radius:10cm

given perpendicular distance from the centre to the chord:6cm

join the two ends of the chord from the centre i.e.join oa and ob.

two right angled triangles are formed.

apply Pythagoras theorem to each triangle and find the base of the triangles

each base of triangle:

√10^2-6^2

√100-36

√64

8cm

then the triangles' bases are 8+8 cm

=16cm
