Python Math: Calculate arc length of an angle
7. Arc Length Calculator
Write a Python program to calculate the arc length of an angle.
Note: In a planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane.
Sample Solution:
Python Code:
def arclength():
pi=22/7
diameter = float(input('Diameter of circle: '))
angle = float(input('angle measure: '))
if angle >= 360:
print("Angle is not possible")
return
arc_length = (pi*diameter) * (angle/360)
print("Arc Length is: ", arc_length)
arclength()
Sample Output:
Diameter of circle: 9 angle measure: 45 Arc Length is: 3.5357142857142856
