Answer:

x = $3\sqrt{13}$ = 10.8

Step-by-step explanation:

Both problems are done the same way. I will do the first one and you do the second one. OK?

Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,

$6^{2} + 9^{2} = x^{2}$

$x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}$ = 10.8

None of the answer choices are to the nearest tenth. So, I am confused about that.

In the second problem, the answer should be 11.2
