Answer:

[tex]\approx 408.2[/tex] in²

Step-by-step explanation:

The surface area of a cylinder can be represented as [tex]2\pi rh+2\pi r2[/tex]. Let's represent pi as 3.14 and r is 5 and h is 8.

[tex](2\cdot 3.14\cdot 5\cdot8) + (2\cdot 3.14 \cdot 5^2)\\\\251.2 + 157 = 408.2[/tex]

This means the surface area of this cylinder is 408.2 in².

Hope this helped!
