Question

How do you convert 210 degrees to radians?

Answer 1

`color(white)(xx)(7pi)/6color(white)(x) "radian"`

Explanation:

`color(white)(xx)1color(white)(x)"degree"=pi/180color(white)(x) "radian"`

`=>210color(white)(x)"degrees"=(210pi)/180color(white)(x) "radian"`
`color(white)(xxxxxxxxxx)=(210picolor(red)(xx30))/(180color(red)(xx30))color(white)(x) "radian"`
(Multiply both the numerator and denominator by `color(red)30`)
`color(white)(xxxxxxxxxx)=(7pi)/6color(white)(x) "radian"`
