Your answer is 2. Simply do -12.2- -14.2 and you will get 2.
Replace N with 6
6(6+1)(2(6)+1) / 6
(6*7*13) / 6
546 / 6 = 91
Answer is C
7853.98mm
Step-by-step explanation:
Circumference is pi times diameter so the diameter is 100 millimeters
Diameter is 2 times the radius so the radius is 50 millimeters
Area is pi times the radius squared so the area is about 7853.98 millimeters squared
Answer: ![326.72yd^{2}](https://tex.z-dn.net/?f=326.72yd%5E%7B2%7D)
Step-by-step explanation:
To find the surface area of the cylinder you must apply the following proccedure:
- Calculate the surface area of the circles. They are equal, then you can multiply the surface area of a circle by 2:
![A_c=2r^{2}\pi=2(4yd)^{2}\pi=100.53yd^{2}](https://tex.z-dn.net/?f=A_c%3D2r%5E%7B2%7D%5Cpi%3D2%284yd%29%5E%7B2%7D%5Cpi%3D100.53yd%5E%7B2%7D)
Where r is the radius.
- Calculate the surface area of the rectangle:
![SAr=l*w](https://tex.z-dn.net/?f=SAr%3Dl%2Aw)
Where l is the lenght and w is the width.
(The length is the circumference of the circle)
Then:
![SAr=(2(4yd)\pi)(9yd)=226.19yd^{2}](https://tex.z-dn.net/?f=SAr%3D%282%284yd%29%5Cpi%29%289yd%29%3D226.19yd%5E%7B2%7D)
- Add the areas obtained.
The result is:
![SA=100.53yd^{2}+226.19yd^{2}=326.72yd^{2}](https://tex.z-dn.net/?f=SA%3D100.53yd%5E%7B2%7D%2B226.19yd%5E%7B2%7D%3D326.72yd%5E%7B2%7D)
