hi just looking the conversions, from degree to radians. I don't understand pie^r, especially the ^r

could someone give me an example so i can see it work. Thanks for your time

2. There are 360 degrees in a full circle and there are $2\pi$ radians in a full circle. The conversion factor from degrees to radians is therefore $\frac{2\pi}{360} = \frac{\pi}{180}$.

3. Thanks for the quick reply, was confused what the r symbol meaned.

Here are some examples for you. Convert the following degrees to radians:

1) 30 degrees = __________ radians.

$30\left(\frac{\pi}{180}\right)=\frac{30 \pi}{180}=\frac{\pi}{6}$ radians.

2) 150 degrees = _________ radians.

$150\left(\frac{\pi}{180}\right)=\frac{150 \pi}{180}=\frac{5 \pi}{6}$ radians.

5. i was a little confused by the first explanation of radians, but with the examples, it really helps thank you soo much
