Answer:
326.56 in².
Step-by-step explanation:
<u>Mathematics: Define/explain.</u>
<u>SURFACE AREA:</u> The measure of the total area that an object occupies.
The formula for finding the surface area for a cylinder is:
![SA=2\pi r^2+2\pi rh](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20r%5E2%2B2%5Cpi%20rh)
![r-radius](https://tex.z-dn.net/?f=r-radius)
![h-height](https://tex.z-dn.net/?f=h-height)
<u>Mathematics: Solve.</u>
According to the image, the cylinder has a height of 9 inches and a base radius of 4 inches.
Now, we can plug the numbers into the formula.
![SA=2\pi 4^2+2\pi4*9- (2*3.14*4*4)+(2*3.14*4*9)=326.56.](https://tex.z-dn.net/?f=SA%3D2%5Cpi%204%5E2%2B2%5Cpi4%2A9-%20%282%2A3.14%2A4%2A4%29%2B%282%2A3.14%2A4%2A9%29%3D326.56.)
<u>Mathematics: Conclude.</u>
Therefore, the surface area of this cylinder is 356.56 in².
