Hello!
To convert radians to degrees, we have to multiply them by [tex]180/ \pi [/tex].
Let's multiply.
[tex]4*180/ \pi [/tex]
≈ 229.18311805
Please note that since we are using [tex] \pi [/tex], we need to use the approximation sign.
4 radians ≈ 229.18311805°
You can feel free to let me know if you have any questions regarding this!
Thanks!
