Answer:
x= -6
Step-by-step explanation:
The number (x) that is (=) 10 less than (-) 6
x = 6 - 10 Subtract
x = -4

I’m assuming you want to work out the area
area = length x width
area = 10 x 8
area = 80 inches^2
Answer: Option A.
Step-by-step explanation:
You need to use this formula for calculate the surface area of the right cylinder:
![SA=2\pi r^2+2\pi rh](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20r%5E2%2B2%5Cpi%20rh)
Where "r" is the radius and "h" is the height.
You can identify in the figure that:
![r=8units\\h=3units](https://tex.z-dn.net/?f=r%3D8units%5C%5Ch%3D3units)
Knowing this, you can substitute these values into the formula
, therefore you get that the surface area of this right cylinder is:
![SA=2\pi (8units)^2+2\pi (8units)(3units)](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20%288units%29%5E2%2B2%5Cpi%20%288units%29%283units%29)
![SA=176\pi\ units^2](https://tex.z-dn.net/?f=SA%3D176%5Cpi%5C%20units%5E2)
