    1507m²

    Step-by-step explanation:

    Given parameters:

    Radius of cylinder = 12m

    Height of cylinder = 8m

    π = 3.14

    Unknown:

    Surface Area of cylinder = ?

    Solution:

    The surface area of any body is the sum of all the area that covers a body.

    For a cylinder, the surface area is given as;

    SA = 2πr² + 2πrh

    Where SA = Surface Area

    r = radius of cylinder

    h = height of cylinder

    Now input the parameters in the given equation and solve;

    SA = (2 x 3.14 x 12²) + (2 x 3.14 x 12 x 8)

    SA = 904.32‬ + 603.264‬

    SA = 1507.584‬m² = 1507m²
