Answer:
Step-by-step explanation:
1. A given chord on a circle is perpendicular to a radius through its center, and it is at a distance less that the radius of the circle.
2. A circle of center O has a radius of 13 units. If a chord AB of 10 units is drawn at a distance, d, to the center of the circle, determine the value of d.
3. From question 2, the radius = 13 units, length of chord = 10 units and distance of chord to center of the circle is d.
A radius that meet the chord at center C, and divides it into two equal parts.
So that;
AC = CB = 5 units
Applying Pythagoras theorem to ΔOCB,
OC = d, CB = 5 units and OB = 13 units
=
+ ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
169 = 25 + ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
169 - 25 = ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
144 = ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
⇒ d = ![\sqrt{144}](https://tex.z-dn.net/?f=%5Csqrt%7B144%7D)
= 12 units
Therefore, the chord is at a distance of 12 units to the center of the circle.
