can someone help me with confeverting angle from radians to degrees

OpenStudy (anonymous):

to convert from radians to degrees, just multiply the angle by 180/\(\pi\) like 2pi/3 radians = 2pi/3 * 180/pi = 2*180/3 = 120 degrees.

OpenStudy (anonymous):

do you have any specificangle in radians you want to convert in degrees ?

OpenStudy (anonymous):

YES!!!! 225 degrees and 150 degrees 135 degrees 315 degrees

OpenStudy (anonymous):

those are angles in degrees, do you want to convert them into radians ?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

ok, then to convert from radians to degrees, just multiply the angle by π/180 like i will do 150 degrees for you, you do other 3 150 degrees = 150* π/180 = (150/180)π = 5π/6 radians got this ?

OpenStudy (anonymous):

kinda

OpenStudy (anonymous):

***to convert from degree to radians ok, then you try for 225 degrees.

OpenStudy (anonymous):

225*π/180 =... ?

OpenStudy (anonymous):

all i get is 3.926990817

OpenStudy (anonymous):

yes, but don't you want the answer in terms of pi ? if not then 3.927 radians is absolutely correct for 225 degrees :)

OpenStudy (anonymous):

yes i do want it in pi

OpenStudy (anonymous):

so, just reduce 225/180 then append pi in the end

OpenStudy (anonymous):

how do you do that on a texas instrument ti-83 plus

OpenStudy (anonymous):

sorry, i don't have that. but i don't think you even need a calculator for this.

OpenStudy (anonymous):

ok give me a second

OpenStudy (anonymous):

sure, take your time :)

OpenStudy (anonymous):

5/4?

OpenStudy (anonymous):

good! :) so, 225 degrees = 5pi/4 radians .

OpenStudy (anonymous):

thx

OpenStudy (anonymous):

i hope you can do other 2 ?

OpenStudy (anonymous):

oh, and since you are new here, \(\Huge \mathcal{\text{Welcome To OpenStudy}\ddot\smile} \) if you have any doubts browsing this site, you can ask me, or to an ambassador (with an encircled A before their name). Have fun learning with Open Study! :)
