Question

Transforme em radiano as seguintes medidas de arcos.

(A) 50°

(B) 140°

(C) 230°

(D) 340°

(E)720°

Answer 1

(A)

$50° = \frac{50\pi}{180} = \frac{5\pi}{18}$

(B)

$140° = \frac{140\pi}{180} = \frac{7\pi}{9}$

(C)

$230° = \frac{230\pi}{180} = \frac{23\pi}{18}$

(D)

$340° = \frac{340\pi}{180} = \frac{17\pi}{9}$

(E)

$720° = \frac{720\pi}{180} = 4\pi$
