This is for understanding purposes only.

The basics are;

one radian is the angle subtended at the centre of a circle by an arc that is the same length as the radius. From this a person can find the number of radians in a full turn, i.e. 360 degrees.

But what if you only wanted to find the number of radians for any given number of degrees less than 360 degrees?

I am a bit at a loss here because I have a table of worked values, but they don't cover every number of degrees between 0 and 360?

Also the table of values and all data previous to it does not give any example how the conversion has been completed, i.e

30 degrees = pi/6

3.141 / 6 = 0.52

To me something is missing, they do not balance?

Can anyone advise what is missing please.

Thanks

Found the solution to the problem,

3.141 / 6 = 0.52 x 57.2 = 30 degrees.

The above works for any number of degrees between 0 and 360
