Answer:

$3 \sqrt{5}$

Step-by-step explanation:

x is the center of the circle.

the chord of length 12 can be splitted into two parts of 6 length each.

since the radius does not change when it touches another end of the circle, we can safely calculate our radius to be the hypotenuse of the triangle formed by the length of the chord and 3.

The explanation is given in the picture

Answer:

∠AB=9

Step-by-step explanation:

the pyagrothyes therom= $a^{2}$ + $b^{2}$ = $c^{2}$

to find ∠AB we need to find the height of the triangle.

replace the variables:

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

= $9^{2}$ - $6^{2}$ = $a^{2}$

simplify:

81-36= $\sqrt{45}$

now we solve for ∠AB

replace the variables:

$6^{2}$ + $\sqrt{45}$ = $c^{2}$

simplify:

36+45= $\sqrt{81}$

$\sqrt{81}$ =9

I hope this helps you!!

have a nice day!!

So 81/9=9 so area of pantry is 9

3 times x=9
3x=9
divide both sides by 3
x=3
