    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
