Sequential control statement

Write a program to calculate area and  circumference of circle.

-----------------------------------------------------------------------------------

#include<stdio.h>

int main() {

   int rad;

   float PI = 3.14, area, ci;

   printf("\nEnter radius of circle: ");

   scanf("%d", &rad);

   area = PI * rad * rad;

   printf("\nArea of circle : %f ", area);

   ci = 2 * PI * rad;

   printf("\nCircumference : %f ", ci);

   return (0);

}

Result

Copy code from here:-

#include<stdio.h> int main() { int rad; float PI = 3.14, area, ci; printf("\nEnter radius of circle: "); scanf("%d", &rad); area = PI * rad * rad; printf("\nArea of circle : %f ", area); ci = 2 * PI * rad; printf("\nCircumference : %f ", ci); return (0); }
