Answer:
Step-by-step explanation:
1
The correct answer is: "
" .
____________________
<u>Step-by-step explanation</u>:
Based on the assumption that the "1" repeats infinitely; in the given value:
" 33.61111111 ...." ;
_______
Note that the "611" ; after the decimal point; this goes to the "thousandths";
place (is "3 (three) digits long.").
_______
As such; we rewrite the number as:
_______
"
" ;
and we multiply BOTH the "numerator" And the "denominator" by: "1000" :
_______
→ "
" ;
to get:
→ "
" ; → which cannot be reduced any further.
_______
The correct answer is: "
" .
_______

Answer:
![A=81\pi $ m^2](https://tex.z-dn.net/?f=A%3D81%5Cpi%20%24%20m%5E2)
Step-by-step explanation:
Circumference of the column ![=18\pi $ meters](https://tex.z-dn.net/?f=%3D18%5Cpi%20%24%20meters)
Circumference of a circle![=2\pi r](https://tex.z-dn.net/?f=%3D2%5Cpi%20r)
Therefore:
![2\pi r =18\pi $ meters\\2r=18\\r=18 \div 2\\$Radius, r=9 meters](https://tex.z-dn.net/?f=2%5Cpi%20r%20%3D18%5Cpi%20%24%20meters%5C%5C2r%3D18%5C%5Cr%3D18%20%5Cdiv%202%5C%5C%24Radius%2C%20r%3D9%20meters)
Area of a Circle ![=\pi r^2](https://tex.z-dn.net/?f=%3D%5Cpi%20r%5E2)
Since radius of the cross section of the column =9 meters
Area of the cross section of the column
![=\pi *9^2\\=81\pi $ m^2](https://tex.z-dn.net/?f=%3D%5Cpi%20%2A9%5E2%5C%5C%3D81%5Cpi%20%24%20m%5E2)
True I think cause it’s divided by 5
Formula for the perimeter of a quarter circle: C = ((pi x 2r) / 4) + 2r
C = ((3.14 + 12) / 4) + 12
C = 3.785 + 12
C = 15.79 meters
Hope this helps! :)
