Chapter 6, Problem 4RE

To determine

Convert the angle in degree to radian as a multiple of $\pi$ .

Answer to Problem 4RE

  $\frac{\pi }{12}$

Explanation of Solution

Given information:

  ${15}^{°}$

Formula used:

  $Degree\times \frac{\pi }{{180}^{°}}=Radians$

  $\begin{array}{l}Degree\times \frac{\pi }{{180}^{°}}=Radians\\ {15}^{°}\times \frac{\pi }{{180}^{°}}=Radians\\ \boxed{\frac{\pi }{12}=Radians}\end{array}$
