well, again, recall, there are 180° in π radians, let's now check how many degrees in 1 radian then.

[tex]\bf \begin{array}{ccll} de grees&radians\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 180&\pi \\ d&1 \end{array}\implies \cfrac{180}{d}=\cfrac{\pi }{1}\implies \cfrac{180\cdot 1}{\pi }=d[/tex]

that many degrees in 1 radian, just 1 radian.

well, how close are their sizes?  surely you'd know.
