Question

In a circle of radius 10 cm, the length of chord whose distance is 6 cm from the centre is (A) 4 cm (B) 5 cm (C) 8 cm (D) 16 cm

Answer 1

solution

data

radius=10cm

distance from the center=6cm

length of chord=?

using pythagoras theorem

a²=b²+c²

⇒c=√a²-b²

c=√10²-6²

c=√100-36

c=√64

c=8

but 2 radius=diameter

⇒r=8/2

r=4

Answer 2

Answer:

the first answer is the right answer
