Answer: ![18.94\°](https://tex.z-dn.net/?f=18.94%5C%C2%B0)
Step-by-step explanation:
The exterior angle of a regular polygon of
sides is given by:
![\frac{360\°}{n}](https://tex.z-dn.net/?f=%5Cfrac%7B360%5C%C2%B0%7D%7Bn%7D)
In the case of a 19-side polygon ![n=19](https://tex.z-dn.net/?f=n%3D19)
Hence:
![\frac{360\°}{19}=18.94\°](https://tex.z-dn.net/?f=%5Cfrac%7B360%5C%C2%B0%7D%7B19%7D%3D18.94%5C%C2%B0)
Answer:
The answer is 22.
Explanation:
Multiply -1 by -9.
![13 + 9](https://tex.z-dn.net/?f=13%20%2B%209)
Add 13 + 9.
![22](https://tex.z-dn.net/?f=22)

Answer:
![f(x)=-\frac{1}{2}x +1](https://tex.z-dn.net/?f=f%28x%29%3D-%5Cfrac%7B1%7D%7B2%7Dx%20%2B1)
Step-by-step explanation:
Slope intercept form is: ![f(x)=mx+b](https://tex.z-dn.net/?f=f%28x%29%3Dmx%2Bb)
<h2>
Find the Slope:</h2>
Choose 2 points on the graph:
(0,1) (2,0)
Find the slope of the two points:
![\frac{0-1}{2-0}=-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B0-1%7D%7B2-0%7D%3D-%5Cfrac%7B1%7D%7B2%7D)
![m=-\frac{1}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B2%7D)
<h2>Find the Y-Intercept</h2>
The y-intercept, or the point that the line crosses on the y axis, is (0,1).
![b=1](https://tex.z-dn.net/?f=b%3D1)
![f(x)=-\frac{1}{2}x +1](https://tex.z-dn.net/?f=f%28x%29%3D-%5Cfrac%7B1%7D%7B2%7Dx%20%2B1)
We know that the equation for Diameter is r^2(2*r), thus:
12/2=6
Your radius is 6.
A=
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r^2 (pi*r^2)
Thus, your area is 113.1
