Question 552827
<pre>
You must not have gotten to radian measure.
See if this is the way you were taught.  It's the same answer.

s = {{{pi/180}}}·r·<font face = "symbol">q</font>

20 = {{{pi/180}}}·9·<font face = "symbol">q</font>
 
The 9 will divide into the 180 and give 20 on the bottom:

20 = {{{pi/20}}}·<font face = "symbol">q</font>
 
Now we multiply both sides by 20

400 = <font face = "symbol">p</font>·<font face = "symbol">q</font>

Now we divide both sides by <font face = "symbol">p</font>

{{{400/pi}}} = <font face = "symbol">q</font>

127.3239545° = <font face = "symbol">q</font>

To the nearest degree is 127°.  Same as the other one I posted here.
