can someone give step by step on what to do?

Answer:
[tex]SA=14.28^{2}[/tex]
Step-by-step explanation:
In the Equation it asks for 3 things; pi (3.14), r (The radius), and h (the height).
In the question, it says that the radius is 1 foot and that the height is 4 feet. From there all you need to do is insert those numbers where it's shown in the equation. This makes the equation go from this:
[tex]SA=2\pi r^{2} + 2\pi r h[/tex]
To this: [tex]SA=2(3.14)(1^{2}) + 2(1)(4)[/tex]
From there you follow PEMDAS/GEMDAS. And should have your answer.
