Problem Statement

luc002.c

The length and breadth of a rectangle and radius of a circle are input through the keyboard. Write a program to calculate the area and perimeter of the rectangle, and the area and circumference of the circle.

Source Code

#include <stdio.h>
#include <math.h>
int main()
{
	double len, bre, r, area_r, per, area_c, cir;
	printf("Enter the length and breadth of the rectangle : ");
	scanf("%lf %lf", &len, &bre);
	printf("Enter the Radius of the circle : ");
	scanf("%lf", &r);
	area_r = len * bre;
	per = 2 * (len + bre);
	area_c = M_PI * r * r;
	cir = 2 * M_PI * r;
	printf("\nArea of Rectangle       : %lf"
		   "\nPerimeter of Rectangle  : %lf"
		   "\nArea of Circle          : %lf"
		   "\nCircumference of Circle : %lf",
		   area_r, per, area_c, cir);
	return 0;
}
