Explicação passo a passo:
[tex]\mathsf{l = \dfrac{\alpha .\pi .r}{180}}[/tex]
[tex]\mathsf{198 = \dfrac{\alpha .(3,14) .324}{180}}[/tex]
[tex]\mathsf{198 = \dfrac{\alpha .(3,14) .324}{180}}[/tex]
[tex]\mathsf{1.017,36.\alpha = 35.640}[/tex]
[tex]\mathsf{\alpha = \dfrac{35.640}{1.017,36}}[/tex]
[tex]\boxed{\boxed{\mathsf{\alpha \approx 35\textdegree}}}\leftarrow\textsf{letra B}[/tex]
