Lets write a C program to convert angle from Degree to Radian.

Formula To Convert Degree To Radian
radian = degree x (M_PI / 180.0);
where M_PI is a constant present in header file / library file math.h and its approximately equal to 3.14;

Note: Trigonometric Ratios like Sin, Cos, Tan etc take radian value as input and not degrees. So its important to learn how to convert angles from degree to radian.
