The key is to convert between radians and degrees using the relationship $\pi \text{ radians} = 180°$. Since $\pi \approx 3.14$, one radian equals roughly $\frac{180°}{3.14} \approx 57.3°$. This comparison shows whether a radian is larger or smaller than your target angle—no calculator needed, just the fundamental conversion ratio.
