Answer 2

Explanation:

49.34 cm is the required length of the chord.

Step-by-step explanation:

According to the Question

It is given that,

Radius of circle OA = 25cm

Distance of its Chord from the centre ,BO = 4cm

we need to calculate the length of the Chord. So,We will use here the Pythagoras Theorem.

AO² BO² + AB²

Substitute the value we get

25² 4² + AB²

625 = 16+ AB²

625-16 AB²

609AB²

AB= √609

AB= 24.67cm

As we know that distance of its Chord from the the centre is perpendicular bisector of the chord.

So, the length of the chord is twice AB

Length of Chord = 2AB

Length of Chord = 2×24.67

Length of Chord = 49.34 cm

Hence, the length of the chord is 49.34 cm (approx)
