It's just a change in scale. \(\displaystyle 2.158 \text{ rad } = \frac{ 2.158 \text{ rad } \pi }{ \pi} = \frac{2.158 \text{ rad }}{3.1415926535} \cdot \pi \approx 0.687 \pi \text{ rad }\)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.

The value of 2.158 radians in terms of Pi is approximately 0.687 Pi.
To convert radians to terms of Pi, simply divide the value of radians by Pi.
The formula for converting radians to terms of Pi is radians / Pi = Pi terms.
We use Pi when measuring angles in radians because it is a mathematical constant that represents the ratio of a circle's circumference to its diameter, and is used to convert between degrees and radians.
Yes, for example, 1.5 radians would be equivalent to approximately 0.477 Pi, and 3 radians would be equivalent to approximately 0.955 Pi.
