Write a program to obtain values n and s from user and print area of polygon.

Q. Area of regular polygon can be computed as :

½ n sin (360 / n ) s²

Where n = number of sides and s = length from center to a corner .

Write a program to obtain values n and s from user and print area of polygon .

Answer =

 

 

 

import math 
s = float(input("Enter the length from center to a corner :- "))
n = int(input("Enter the number of sides :- "))
sin = math.sin(360 / n )
print ( 1/2 * n * sin * s ** 2)

Output :-

Enter the length from center to a corner :- 50
Enter the number of sides :- 8
8509.035245341185
>>>

Enter the length from center to a corner :- 89
Enter the number of sides :- 6
