    527.52 in2 of paper.

    Step-by-step explanation:

    The area of the water bottle label can be calculated by the product of its circunference length and its height.

    The length of its circunference is calculated as:

    C = 2 * pi * r

    C = 2 * 3.14 * 2 = 12.56 inches

    Now, to find the area of the label, we just multiply the length by the height:

    Area = C * h = 12.56 * 3.5 = 43.96 in2

    As we want to know the amount of paper for 12 water bottles, we multiply the area of one label by 12:

    Total Paper = 12 * 43.96 = 527.52 in2

    It will be needed 527.52 in2 of paper.
