Python Math: Calculate the area of sector

Python Math: Exercise-8 with Solution

Write a Python program to calculate the area of a sector.
Note: A circular sector or circle sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.

Sample Solution:-

Python Code:

def sectorarea():
    pi=22/7
    radius = float(input('Radius of Circle: '))
    angle = float(input('angle measure: '))
    if angle >= 360:
        print("Angle is not possible")
        return
    sur_area = (pi*radius**2) * (angle/360)
    print("Sector Area: ", sur_area)

sectorarea()

Sample Output:

Radius of Circle: 4                                                                                           
angle measure: 45                                                                                             
Sector Area:  6.285714285714286

Python: Tips of the Day

Merging strings:

You can use join method to combine strings. Very useful indeed.

lst="Asia, Europe, Africa, Australia"
str=",".join(lst)
print(str)

Output:

A,s,i,a,,, ,E,u,r,o,p,e,,, ,A,f,r,i,c,a,,, ,A,u,s,t,r,a,l,i,a
