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
