A chord drawn 5 cm away from the center of a circle of radius 13 cm. Calculate the length of the chord
A
7cm
B
9cm
C
12cm
D
24cm
correct option: d
x2 + 52 = 132
x2 + 25 = 169
x2 = 144
x = √ 144
= 12
Length of the chord AB = 2x
2*12= 24cm
x2 + 25 = 169
x2 = 144
x = √ 144
= 12
Length of the chord AB = 2x
2*12= 24cm
