# The radian is the standard unit of angular measure, used in many areas of mathematics. An angle's measurement in radians is numerically equal to the length of a corresponding arc of a unit circle; one radian is just under 57.3 degrees (when the arc length is equal to the radius).

pi=22/7  
degree = float(input("Input degrees: "))  
radian = degree*(pi/180)  
print(radian)
