    Answer:

    The lateral area of the cylinder is 678cm²

    Step-by-step explanation:

    To calculate the lateral area of ​​the cylinder we have to calculate the circumference and multiply it by the height

    To solve this problem we need to use the circumferenc formula of a circle:

    c = circumference

    r = radius = 9cm

    π = 3.14

    c = 2π * r

    we replace with the known values

    c = 2 * 3.14 * 9cm

    c = 56.52cm

    The length of the circumference is 56.52cm

    lateral area = c * h

    56.52cm  * 12cm = 678.24 cm²

    round to the nearest whole number

    678.24 cm² = 678cm²

    The lateral area of the cylinder is 678cm²
