Young Modulus Homework Help Please!

    1. The problem statement, all variables and given/known data
    Calculate the stress in a wire of diameter 0.35mm when the tension in the wire is 50N.


    2. Relevant equations
    Stress=F/A


    3. The attempt at a solution
    0.25/2=0.125
    0.125/100=1.25x10"-3

    Pi x 0.00125"2 = 1.542x10"-5

    50/1.542x10"-5 = 3242542.153 Pa


    Are my workings correct?

    Is the wire diameter 0.25 mm or 0.35 mm?
