    0.25m

    Explanation:

    Using the expression that relates the angular velocity (w) and the linear velocity (v).

    v = wr where;

    w is the angular speed = 128rad/s

    v is the linear speed = 32m/s

    r is the radius

    r = v/w

    r = 32/128

    r = 0.25m

    The radius of the blade is 0.25m
