Answer:


\approx 408.2 in²

Explanation:

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


(2\cdot 3.14\cdot 5\cdot8) + (2\cdot 3.14 \cdot 5^2)\\\\251.2 + 157 = 408.2

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

Hope this helped!
