Answer:

The answer to your question is 301.44 m²

Step-by-step explanation:

Data

height = 13 m

diameter = 6 meters

Formula

Area of a cylinder = 2πr² + 2πrh

- Substitution

Area of a cylinder = 2(3.14)(3)² + 2(3.14)(3)(13)

- Simplification

Area of a cylinder = 56.52 + 244.92

-Result

Area of a cylinder = 301.44 m²
