    Answer: 229°

    Step-by-step explanation:

    Hi, to answer this question we have to multiply the radians by 180/π.

    Since we have 4 radians, the expression is:

    4 x (180/π) = 229.18 degrees

    Rounding to the nearest degree:

    229 degrees (because the first number after the point is less than 5 )

    Feel free to ask for more if needed or if you did not understand something.

    Question:

    A. 13°

    B. 45°

    C. 229°

    D. 720°

    Answer:

    The correct option is;

    C. 229°

    Step-by-step explanation:

    Here we have

    360° = 2·π radians which is the angle at the center of a circle, where the circumference of the circle is 2·π·r and r = 1

    Therefore;

    1 radian = 360°/(2·π)

    Hence, 4 radian = 4 × 360°/(2·π) = 720/π = 229.183°

    Therefore, the value of 4 radians converted to degrees is 229° after the exact figure is rounded to the nearest whole number.
