Answer:
or ![316.62\ cm^2](https://tex.z-dn.net/?f=316.62%5C%20cm%5E2)
Step-by-step explanation:
step 1
Find the area of complete circle
The area of the circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
we have
![r=11\ cm](https://tex.z-dn.net/?f=r%3D11%5C%20cm)
substitute
![A=\pi (11)^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%2811%29%5E%7B2%7D)
![A=121\pi\ cm^2](https://tex.z-dn.net/?f=A%3D121%5Cpi%5C%20cm%5E2)
step 2
Find the area of the sector
Remember that the area of the complete circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of the region by a central angle of 300 degrees
![\frac{121\pi}{360^o}=\frac{x}{300^o}\\\\x=121\pi (\frac{300^o}{360^o})\\\\x=\frac{36,300}{360}\pi\ cm^2](https://tex.z-dn.net/?f=%5Cfrac%7B121%5Cpi%7D%7B360%5Eo%7D%3D%5Cfrac%7Bx%7D%7B300%5Eo%7D%5C%5C%5C%5Cx%3D121%5Cpi%20%28%5Cfrac%7B300%5Eo%7D%7B360%5Eo%7D%29%5C%5C%5C%5Cx%3D%5Cfrac%7B36%2C300%7D%7B360%7D%5Cpi%5C%20cm%5E2)
simplify
----> exact value
Find the approximate value
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
![x=\frac{605}{6}(3.14)=316.62\ cm^2](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B605%7D%7B6%7D%283.14%29%3D316.62%5C%20cm%5E2)
The figure of the figure would be figuring out the figurative
Answer:
Infinity or All real numbers
Step-by-step explanation:
2x-7+19=6x-4x+12
2x+12=2x+12
-12 -12
2x=2x
/2 /2
x=x
I believe its additive Inverse Property
Answer:
(4-2)x12=24
(7-3)x12=48
24+24+48+48=144
