Calculate arc length of an angle

Calculate 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.

Test Data:

Diameter of a circle: 8

Angle measure: 45

Expected output:

Arc Length is: 3.142857142857143

def arclength():
    pi = 22/7
    diameter = float(input('Diameter of a 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)

# test
arclength()

Output:

Diameter of a circle: 9
Angle measure: 45
Arc Length is:  3.5357142857142856
