Answer:
6 units
Explanation:
One side of the triangle is 4 cm, since the chord is 4 units away from the center, and the hypotenuse is 5 cm. To find the remaining side, we use the pythagorean theorem, 5^2-4^2=remaining side^2, remaining side = 3. To get the length of the chord, we double 3 and get 6 units.
