Question

1- Converta em graus ou radianos as seguintes medidas:
a)10/2 π rad=
b) 5/2 π rad =
c) 300°=
d) 120° =


Qualquer dúvida tem a foto certinha.

Answer 1

$\large\boxed{\begin{array}{l}\tt a)~\sf\dfrac{10}{2}\pi~rad=5\cdot180^\circ=900^\circ\\\\\tt b)~\sf\dfrac{5}{2}\pi~rad=\dfrac{5}{2}\cdot180^\circ=5\cdot90^\circ=450^\circ\\\\\tt c)~\sf300^\circ=\dfrac{300\div60}{180\div60}\pi~rad=\dfrac{5}{3}\pi~rad\\\\\tt d)~\sf120^\circ=\dfrac{120\div60}{180\div60}\pi~rad=\dfrac{2}{3}\pi~rad\end{array}}$
