    For this case we have the following function:

    f = 1 / (2π√LC)

    Clearing L we have:

    √LC = 1 / (2πf)

    LC = (1 / (2πf)) ^ 2

    L = (1 / C) * (1 / (2πf)) ^ 2

    Substituting values:

    L = (1 / 0.0001) * (1 / (2 * 3.14 * 6.2)) ^ 2

    L = 6.596253438

    Round to the nearest tenth:

    L = 6.6

    Answer:

    L = 6.6

    In this situation, you have to use the equation

    f = 1 / (2π√LC)

    To find L

    √LC = 1 / (2πf)

    LC = (1 / (2πf)) ^ 2

    L = (1 / C) * (1 / (2πf)) ^ 2

    Substitute the values:

    L = (1 / 0.0001) * (1 / (2 * 3.14 * 6.2)) ^ 2

    L = 6.596253438

    L = 6.6

    So the Answer is this:

    L = 6.6
