Question

Basic program to calculate the circumference of a circle​

Answer 1

Answer:

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);

Answer 2

• int main() { int rad;
• float PI = 3.14, area, ci; printf("\nEnter radius of circle: ");
• float PI = 3.14, area, ci; printf("\nEnter radius of circle: ");scanf("%d", &rad); area = PI * rad * 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;
• 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);
