Answer: Option A.
Step-by-step explanation:
You need to use this formula for calculate the surface area of the right cylinder:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where "r" is the radius and "h" is the height.
You can identify in the figure that:
[tex]r=8units\\h=3units[/tex]
Knowing this, you can substitute these values into the formula [tex]SA=2\pi r^2+2\pi rh[/tex], therefore you get that the surface area of this right cylinder is:
[tex]SA=2\pi (8units)^2+2\pi (8units)(3units)[/tex]
[tex]SA=176\pi\ units^2[/tex]
