Solution

VerifiedStep 1

1 of 5To convert from degrees to radians, multiply by $\dfrac{\pi}{180\text{\textdegree}}$ .

$\begin{align*} \text{ a. } \ 1\text{\textdegree} &= 1\text{\textdegree} \left( \dfrac{\pi}{180\text{\textdegree}} \right)\\ & = \dfrac{\pi}{180 }\\ & = \dfrac{3.14}{180 }\\ 1\text{\textdegree} & \approx 0.017 \ rad \end{align*}$

Thus, $1\text{\textdegree} \approx 0.017\ rad$
