To change from degrees to radians, multiply by (pi)/180

To go from radians to degrees, multiply by 180/(pi)

Use a graphing calculator. My TI-84 could do it, I think. If you have a TI-83 or higher, then you go into Mode, and select “radians.” Then just type 225!

Consider this:

180 deg = pi rads, so,

1 deg = pi/180 rads, so,

225 deg = 225*pi/180 rads. 45 is a common factor of 180

and 225, so cancel by 45, and you get:

225 deg = 5pi/4 rads. Hope this helps, Twiggy.
