What is Decagon?
Given with side, the task is to calculate the perimeter of decagon. Decagon is a type of polygon with 10-sides that’s why it is also known as 10-gon polygon. It have 10 vertices and edges. A regular decagon has sides of equal length and each internal angle of degree 144.
Given below is the figure of Decagon
To calculate the volume and surface area of Frustum of cone there is a formula
Perimeter = 10 * Side
Example
Input-: side=10 Output-: perimeter of Decagon is : 100 Input -: side = 20 Output -: perimeter of Decagon is : 200
Algorithm
Start Step 1 -> declare function for finding the perimeter void perimeter(int n) declare variable as int perimeter set perimeter=10*n print perimeter step 2 -> In main() declare int n=10 perimeter(n) Stop
Example
#include <stdio.h>
// Function for finding the perimeter
void perimeter(int n){
int perimeter;
perimeter = 10 * n;
printf("perimeter of Decagon is : %d", perimeter);
}
int main(){
int n=10;
perimeter(n);
return 0;
}Output
perimeter of Decagon is : 100
