The correct answer is D. [tex]72 \pi[/tex] [tex]units^{2}[/tex]
Explanation:
The surface area refers to the sum of the area of all sides in a 3D shape such as a cube or cylinder. Additionally, the formula used to calculate the surface area varies with the shape. In the case of cylinders, the general formula is [tex]A = 2\pi r h + 2\pi r^{2}[/tex]. Moreover in this, the r represents the radius (measure from the center of a circle to any side), while the h represents height. Below, all the process is shown:
[tex]A = 2\pi r h + 2\pi r^{2}[/tex]
[tex]A = 2\pi (8 x 3) + 2\pi 8^{2}[/tex]
[tex]A = 2\pi 24 + 2\pi 64[/tex]
[tex]A = 48\pi + 128\pi[/tex]
[tex]A = 176\pi[/tex]
In this point, you have the answer without solving [tex]\pi[/tex] (3.1416). This makes option A the correct answer.
