Answer:
Step-by-step explanation:
10 or 14.14cm is the length of the cord
Let the circle's radius be 'r' and the angle that is subtended at the center by the chord be ∅,
We are given that:
r = 10cm
∅ = 90°
Length of the chord = 2r sin ∅/2
= 2 * 10sin (90°/2)
= 20 * sin 45°
= 20 * 1/
= 10
In cm, it would be 14.14 cm
