Question

Radius of a circle is 61cm find the length of a chord which is at a distance of 11 cm from the centre

Answer 1

Answer:

120cm

Step-by-step explanation:

in figure ,

radius of circle is 61 cm, distance between centre of circle and chord 11cm

by Pythagoras theorem

hypt2 =base2 + height2

61×61=base2 + 11×11

3721 = base2 + 121

3721-121 = base2

3600= base2

base = 60

therefore this is the half part of chord

so,

60 x 2= 120

120cm is the length of the chord

Answer 2

Answer :- 120 cm
