CPM Homework Help : INT3 Problem 9-137

Recall the strategies you developed for converting between degrees and radians. 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):
$270^\circ$
