Do you mean pie or pi? There's a big difference: pi is only half the pie!

Let me give you a hint, if x=180, then what is 1 in terms of x? How do you get that right hand side to equal 1?

Once you know what 1

Hope that helps. :)

Second, Since degrees and radians measure the same thing, they are proportional: the ratio of radian measure to degree measure for the same angle is always the same: If an angle has degree measure d and radian measure r, then

[tex]\frac{r}{d}= \frac{\pi}{180}[/itex]

so

[tex]r= d\left(\frac{\pi}{180}\right)= \frac{d}{180} \pi[/tex]

If d= 38 38/180= .21111.
