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
