Is the formula to convert degrees to radians (number * pi/180) the same for all shapes; for example if I wanted to find the sine of an octagon would I do number* pi/1080?

$2\pi$ radians gives you the same angle as $360$ degrees, a complete circle.
$1$ radian gives you the same angle as $360/(2\pi) \approx 57.296$ degrees.
$1$ degree gives you the same angle as $2\pi/360 \approx 0.01745$ radians.
