Question

write an c progam to find area of circle​

Answer 1

Answer:

C Program

C Program#include<stdio.h>

C Program#include<stdio.h>int main() {

C Program#include<stdio.h>int main() {float radius, area;

C Program#include<stdio.h>int main() {float radius, area;printf("\nEnter the radius of Circle : ");

C Program#include<stdio.h>int main() {float radius, area;printf("\nEnter the radius of Circle : ");scanf("%d", &radius);

C Program#include<stdio.h>int main() {float radius, area;printf("\nEnter the radius of Circle : ");scanf("%d", &radius);area = 3.14 * radius * radius;

C Program#include<stdio.h>int main() {float radius, area;printf("\nEnter the radius of Circle : ");scanf("%d", &radius);area = 3.14 * radius * radius;printf("\nArea of Circle : %f", area);

C Program#include<stdio.h>int main() {float radius, area;printf("\nEnter the radius of Circle : ");scanf("%d", &radius);area = 3.14 * radius * radius;printf("\nArea of Circle : %f", area);return (0);

Answer 2

Answer:

#include < stdio.h >

#include < conio.h > #define PI 3.141

int main()

{

float radius, area;

printf("Enter radius of circle\n");

scanf("%f", & radius);

area = PI * radius * radius;

printf("Area of circle : %0.4f\n", area);

getch();

return 0;
