    Answer:d = 0.0219m

    Explanation:

    P = force / area

    Area = πr^2=πd^2/4

    πd^2/4=force/pressure

    πd^2/4=34/90000

    πd^2/4=0.0003778

    πd^2 = 0.0003778*4

    πd^2=0.001511

    Since π=3.142

    d^2 = 0.001511/3.142

    d^2 = 0.000480

    d = square root of 0.000480

    d = 0.0219m
