Answer:
<h2>(2)</h2>
Step-by-step explanation:
Because
not ![=(x-4)(x-4)](https://tex.z-dn.net/?f=%3D%28x-4%29%28x-4%29)
This follows from the formula ![a^2-b^2=(a-b)(a+b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29)

➷ The formula for surface area of a cylinder is:
![2\pi rh + 2\pi r^2](https://tex.z-dn.net/?f=2%5Cpi%20rh%20%2B%202%5Cpi%20r%5E2)
The radius is half the diameter
radius = 40/2 = 20
Substitute the values in
Surface area = ![2\pi (20)(32) + 2\pi (20)^2](https://tex.z-dn.net/?f=2%5Cpi%20%2820%29%2832%29%20%2B%202%5Cpi%20%2820%29%5E2)
Simplify to get an answer of:
surface area = ![2080\pi feet^2](https://tex.z-dn.net/?f=2080%5Cpi%20feet%5E2)

Hey, your answers are :)
A.) n = 68
B.) n = 21/2
C.) n = 77/5
Answer:
833
Step-by-step explanation:
First find the 15% of 56,105;
* 56,105 = x
0.15 * 56,105 = x
882 = x
Now subtract 15% of 56,105 from 56,105;
15% of 56,105 = 882
now;
56,105 - 882 = 833
Hope this helps!
