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.
