    The answer to your question is 9923 cm²

    Step-by-step explanation:

    Data

    radius = 30.8 cm

    height = 20.5 cm

    Surface area = ?

    Process

    1. - Write the formula to calculate the surface area of a cylinder

    SA = 2πr² + 2πrh

    2. - Substitution

    π = 3.14

    SA = 2 (3.14) (30.8) ² + 2 (3.14) (30.8) (20.5)

    3. - Simplification

    SA = 5957.459 + 3965.192

    4. - Result

    SA = 9922.65 cm² or SA = 9923 cm²
