2.158 radians can be expressed as approximately 0.687π radians through a simple conversion process. This involves dividing 2.158 by the value of π (approximately 3.1415926535) to obtain the coefficient of π. The calculation confirms that 2.158 rad = 0.687π rad, providing a clear method for converting radians to a π-based representation.
PREREQUISITESStudents learning trigonometry, educators teaching angle conversions, and anyone needing to express angles in terms of π for mathematical clarity.
It's just a change in scale. [math]2.158 \text{ rad } = \frac{ 2.158 \text{ rad } \pi }{ \pi} = \frac{2.158 \text{ rad }}{3.1415926535} \cdot \pi \approx 0.687 \pi \text{ rad }[/math]yeny said:Hello, can someone show me how 2.158 radians can also be written as .687pi? I need to learn how to do this so I can write my answer in terms of pi as opposed to 2.158.
Thank you in advance.
