How to Write a C- program to compute the circumference of a circle and area of circle.#Programming near me

Write a C- program to compute the circumference of  a circle  and area of circle.#Programming near me #java 8 download.

Consider  a  c-program, which are use to find the circumference of  a circle  and area of circle , and displays the result. Here the complete programs  are  shown as follows……

1: Using Define

#include<stdio.h>

#include<conio.h>

#define pi  3.14

Void main()

{                 

Float r,a,c;

Printf(“Enter the Radius \n”);

Scanf(“%f”,&r);

a=pi*r*r;

c=2*pi*r;

printf(“Area of circle =%f \n”,a);

printf(“Circumference of circle=%f \n”,c);

getch();

}

Input= 4

Output=

Area of circle= 50.240002

Circumference of circle=25.120001

Area and circumference of circle

2:-Using constant

#include<stdio.h>

#include<conio.h>

Void main()

{

Const  float  pi=3.14;      

Float r,a,c;

Clrscr();

Printf(“Enter the Radius \n”);

Scanf(“%f”,&r);

a=pi*r*r;

c=2*pi*r;

printf(“area of circle =%f \n”,a);

printf(“circumference of circle=%f \n”,c);

getch();

}

Input= 4

Output=

Area of circle= 50.240002

Circumference of circle=25.120001

Area and circumferences of circle

3:-Using Float

#include<stdio.h>

#include<conio.h>

Void main()

{                 

Float r,a,c,pi=3.14;

Clrscr();

Printf(“Enter the Radius \n”);

Scanf(“%f”,&r);

a=pi*r*r;

c=2*pi*r;

printf(“area of circle =%f \n”,a);

printf(“circumference of circle=%f \n”,c);

getch();

}

Input= 4

Output=

Area of circle= 50.240002

Circumference of circle=25.120001

 

Area and circumferences of circle
