Question

What is the length of the chord of a circle of radius 10cm if the perpendicular distance
between the centre and the chord is 6cm?

Answer 1

Step-by-step explanation:

radius -chord. 10-6=4 it is the answer

Answer 2

Answer:

16 CM

Step-by-step explanation:

in ∆ AOB, by applying Pythagoras theorem

AO² =. AB² + BO²

10². =. AB² + 6²

AB² = 100 - 36

AB. =. √ 64

AB = 8 CM

as OB is perpendicular to AC. then, AC = AB + BC

length of chord = 2 AB

= 2*8

= 16 CM

if it's right answer plz. .mark as brilliant
