Question

converta em radiano:
41º15'

Answer 1

$180\º$  →  $\pi \text{ rad}$

$41\º15'$  →      $\alpha$

$41\º15'=41\º +\dfrac{15}{60}\º=41\º +0,25\º=41,25\º$

$\dfrac{180}{41,25} = \dfrac{ \pi }{ \alpha }$

$\alpha = \dfrac{ 41,25\pi }{180} = \dfrac{ (41,25).(3,14) }{180} = \dfrac{ 129,525 }{180} =0,72$ $\text{rad}$
