Answer:
The answer is 326.726 in^2.
Step-by-step explanation:
To find the surface area of the cylinder, start by using the formula for the surface area of a cylinder, which is 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex].
To solve for the surface area, plug in the information from the question into the formula. Next, the formula will look like 2[tex]\pi[/tex](4)(9) + 2[tex]\pi[/tex]([tex]4^{2}[/tex]). Then, solve the equation, and the final answer will be 326.726 in^2.
