Answer 1

$~\huge\mid{\boxed{\bf{\blue{Matem\acute{a}tica}}}\mid}$

Para converter 40° em radiano, multiplique $\color{green} {{  }}\frac{\pi}{180°}rad$

$40° \times \frac{\pi}{180°} rad$

• Divida-os por 20°

$40° \div 20° \times \frac{\pi}{180° \div 20°} rad$

$2 \times \frac{\pi}{9} rad$

• Use a propriedade $\color{green} {{ x \times \frac{\pi}{x}rad = \frac{x\pi}{x}rad }}$

Resposta: $\color{green} \boxed{{  \frac{2\pi}{9} rad }}$
