Practical - 5
Aim: Write a program to find the area of Circle. (A = PI * r * r).
Program:
#include <stdio.h>
#include <conio.h>
void main()
{
clrscr();
float PI = 3.14, radius, area;
printf("Enter The Radius = ");
scanf("%f", &radius);
area = PI * radius * radius;
printf("\nThe Area = %f",
area);
getch();
}
Output:
Enter
The Radius = 7
The
Area = 153.860016
Algorithm:
Step-1:
START
Step-2:
Declare PI = 3.14, radius, area.
Step-3:
Enter the value of radius.
Step-4:
area = PI * radius * radius.
Step-5:
Display area.
Step-6:
STOP.
