Help with Radians: Find Angles in Radians

[tenchick19]

I need help with radians.. One of my questions is: An angle of 0 (with line through it) =249 degrees is equivalent to how many radians? Answer in units of rad.
Thanks!

1 degree = $\pi$/180 radians. Angle $\theta$ = 249 degrees. What do you think you should do?

 

[tenchick19]

Would the answer be 4.35 radians?

Yes, but that would be an approximation.

$$249^\circ = \frac{{249\pi }}{{180}}rad = \frac{{83\pi }}{{60}}rad \approx 4.35rad$$

That's what I get, if you're rounding.

I forgot you got to be fast around here.

thank you so much!

Glad we could help

Just a really, really, really small point. Radians, I am sure, can be written as $$\pi ^c$$.

Like I said - a really, realy, really small point.

I never knew that, in my books, they always denoted radians by putting a little R superscript, like so:

$2\pi^R$

Really? I usually use c. I have never seen that before. I expected to R when I studied radians but we use c.
