Chapter 6, Problem 3RE

To determine

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

Answer to Problem 3RE

  $\frac{\pi }{10}$

Explanation of Solution

Given information:

  ${18}^{°}$

Formula used:

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

  $\begin{array}{l}Degree\times \frac{\pi }{{180}^{°}}=Radians\\ {18}^{°}\times \frac{\pi }{{180}^{°}}=Radians\\ \boxed{\frac{\pi }{10}=Radians}\end{array}$
