What is 130° in radians?

$${\mathtt{130}}$$ degrees

 

$${\frac{{\mathtt{130}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{180}}}}$$

 

$${\frac{{\mathtt{13}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{18}}}}$$

 

$${\mathtt{130}}$$ degrees is equal to $${\frac{{\mathtt{13}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}{{\mathtt{18}}}}$$ radians

180° = pi radians  Try to remember this.

 

1° = pi/180 radians

 

130° = 130*pi/180 radians

.

By definition, a 1π radian is equivalent to 180º. Being X the number of radians, by using the rule of three, one has X = (1 rad)(130º)/180º = 13/18π radians.

 

130º = 13/18 π radians.
