CPM Homework Help : CCA2 Problem 7-161

Recall the strategies you developed for converting degrees to radians. How could you reverse that? Convert each of the following angle measures. Be sure to show all of your work.

Hint:

Recall that π radians are equal to $180^\circ$ .

$π$ radians to degrees

$3π$ radians to degrees

$30$ degrees to radians
Step (c):
$30^\circ\left( \frac{\pi}{180^\circ} \right)$

$\frac { \pi } { 4 }$ radians to degrees
Step (d):
$\left( \frac{\pi}{4} \right) \left( \frac{180^\circ}{\pi} \right)$

$225$ degrees to radians
Answer (e):
$\frac{5\pi}{4} \; \text{radians}$

$\frac { 3 \pi } { 2 }$ radians to degrees
Answer (f):
$270^\circ$
