A chord is 4 units from the center of a circle. The radius of the circle is 5 units. What is the length of the cord?
1 answer:
Answer:
6 units
Step-by-step 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.
