Answer:
As per question given details:
a chord 12cm is 8cm distance from the centre of the circle.
Assume that centre of the circle be O and E The mid point of AB. AEO and BEO are both right angled triangle.
i.e AE=
2
12
and EO=8cm, so R the radius of the circle is
[6
2
+8
2
]
=
(36+64)
=
100
=10cm
Now the chord CD is 6cm from O. Let F be the mid point of CD. CFO and DFO are both right angled triangle. FO=6cm and CO=DO=10cm, so
CF=DF
=
[10
2
−6
2
]
=
100−36
=
64
=8cm
So, as per solution
D=2×8=16cm
I hope it's help ful to
