Answer:
y = 16 cm
Step-by-step explanation:
The distance from the center of the concentric circles up to the chord is equal to the radius of the smaller circle. 6.
The distance from the center of the concentric circles to one of the ends of the chords is equal to the radius of the larger circle. 10.
To find the length of the chord (let's call it y)we have this equation:
(y/2)² = 10² - 6² = 64
y²/4 = 64
ý² = 256
y = 16 cm
