Question

how to convert the degree measures to radian measures

Answer 1

multiply degree measures by Π/180

Answer 2

$1 \textdegree =\dfrac{\pi}{180}$

For example: Convert 45° into radian:

$1 \textdegree =\dfrac{\pi}{180}$

$45\textdegree =\dfrac{\pi}{180} \times 45$

$45 \textdegree =\dfrac{45\pi}{180}$

$45 \textdegree =\dfrac{\pi}{4}$

$45 \textdegree =0.785 \text { radian}$
