    I looked at the picture but what do you want help with?

    What is the question?

    Drawing a line from the mass to the center of rotation gives two right triangles with hypotenuse of length 1 and one leg of length .8m.
    You can use the Pythagorean theorem to find the radius of rotation and then calculate both angular velocity and centripetal force. I don't know what else you want since you did not ask a question.
