I do not understand how to get the radian measure of pi....
Wouldn't it just be 180 degrees??? Because of where pi is positioned on a circle?
Can someone please explain this to me?
Thank you!

The basic relationship is that a full circle is either 2π radians or 360 degrees. Dividing both sides by the common factor 2 gives:
π radians = 180 degrees
So, to convert from radians to degrees, multiply by 180/π.
To convert from degrees to radians, multiply by π/180.
If you really meant to convert π degrees to radians, then that would be π²/180 in radian measure. That's almost never going to come up in a problem, though.

are you confused that pi is being in radian somewhere & still every time we use it in every 2nd formula for area, volume & perimeter in geometry?
am i right?
if so, then i would say that you should forget about pi [that we use in formula's ] to be in its pure form.
i mean pi is basically always in radian but we do use it as numerical value constants in our calculations for simplicity sake.
the fact is that when the concept was originally introduced & interpreted, the measures in use were radians etc. just as later, we have had used hours, minutes & seconds in angle measures too just as we do it in time.
so, as a matter of fact, it doesn't really look like a crime if we decide to use it as degree measure alone.
i mean what difference does it make if i use 360 degree instead of 2 pi radian? it isn't going to affect my calculations one bit.
still we are always supposed to have a slice of this & other slice of that & are expected to have a strong constitution.without any constipation. really its too much.
anyways, if your issue was what i thought it is, then welcome to the club.
