CPM Homework Help : A2C Problem 8-81

Recall the strategies developed in class 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 $180º$ .

$π$ 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):
$270°$
