Write a C program to find area and perimeter of Circle.

 

 #include <stdio.h>

 int main() {

   int radius;

   float area, perimeter;    //variable declaration

   

   printf("Enter Radius of circle: ");

   scanf("%d",&radius);      //taking radius as input

   perimeter = 2*3.14*radius;    //formula to find perimeter

   printf("Perimeter of the Circle = %f inches\n", perimeter);

  area = 3.14*radius*radius;    //formula to find area

  printf("Area of the Circle = %f square inches\n", area);

 return(0);

}
