    kinda lost here on this one

    The diameter of a cylinder is specified as 120±0.1 mm. Find the percentage error in the
    diameter.

    The Range would be 119.9 -> 120.1 so that would mean 0.2 * 100 / 120

    NO ?

    The most the diameter will be out by is 1mm.

    So there'll be a maximum error of 0.1 * 100 / 120
