Question

In a circle is 5 cm a chord is drawn if perpendicular is 3 cm. Find the length of the chord.
$r squre = l squre + d squre$
​

Answer 1

Step-by-step explanation:

Let AB be chord

O be centre

OM is perpendicular distance

We know the property that =>

Perpendicular drawn from centre to its chord bisects the chord

Do it will bisect it,

By P. T=>

AO^2 = AM^2 + MA^2

25 = 9 + MA^2

MA = 4

AB = 2MA

AB = 2(4)

AB = 8 cm
