C Program to Calculate Area and Circumference of circle

#include <stdio.h> int main() { int circle_radius; float PI_VALUE=3.14, circle_area, circle_circumf; printf(“\nEnter radius of circle: “); scanf(“%d”,&circle_radius); circle_area = PI_VALUE * circle_radius * circle_radius; printf(“\nArea of circle is: %f”,circle_area); circle_circumf = 2 * PI_VALUE * circle_radius; printf(“\nCircumference of circle is: %f”,circle_circumf); return(0); }
