Given:
[tex]288^{\circ}[/tex]To convert degrees into radians:
We know that,
[tex]\text{Radian}=\theta\times\frac{\pi}{180}[/tex]So, we get
[tex]\begin{gathered} \text{Radian}=288\times\frac{\pi}{180} \\ =\frac{144\pi}{90} \\ =\frac{16\pi}{10} \\ =\frac{8\pi}{5} \end{gathered}[/tex]Thus, the answer is,
[tex]\frac{8\pi}{5}[/tex]
