Answer:
25.298 or 8√(10)
Explanation:
In this problem half of chord QP and the radius of the smaller circle form a right triangle whose hypotenuse is the radius of the larger circle. We can use the pythagorean theorem to find the missing leg, which is half the lentgth of the chord to find the total lenght of teh chord.
a=radius of larger circle
b=half of chord
c=radius of smaller circle
a²=b²+c²
a²-c²=b²
14²-6²=b²
196-36=b²
160=b²
b=√160
b=12.649
2b=chord length
2(12.649)=25.298
The length of the chord is 25.298 or 8√(10)
