Question : 1 Write a C Program to calculates the area (floating point number with two decimal places) of a Circle given it’s radius (integer value). The value of Pi is 3.14
#include <stdio.h>
#define PI 3.14
void main()
{
int radius;
float area;
/* Enter the radius of a circle */
scanf("%d", &radius);
area = PI * radius * radius;
printf("Area of a circle = %5.2f", area);
}
