    904.32m^2

    Step-by-step explanation:

    Surface area of a cylinder

    = 2 pi rh + 2pi r^2

    Given Height h = 7m

    Radius r = 9m and

    Pi = 3.14

    Surface area = 2 x 3.14 x 9 x 7 + 2 x 3.14 x (9) ^2

    2 x 3.14 x 9 x 7

    +

    2 x 3.14 x 9x9

    Simplify each sides

    395.64 + 508.68

    904.32m^2
