# 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
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`
