It also calculates the area and the circumference of the circle.

The values of Length, Breadth and Radius are to be entered through the keyboard.

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 the circumference of the circle.

/*

aor: area of rectangle

por: perimeter of rectangle

aoc: area of circle

coc: circumference of circle

*/

**#include <stdio.h>**

main()

**{**

**float**length, breadth, radius, aor, por, aoc, coc;

printf ("\nEnter the Length and Breadth of the Rectangle: ");

scanf("%f %f", &length, &breadth);

printf("\nEnter the Radius of the Circle: ");

scanf("%f", &radius);

aor = length*breadth;

por= 2*(length+breadth);

aoc = 3.14*radius*radius;

coc = 2*radius*3.14;

printf("\nThe area of the rectangle is: %f", aor);

printf("\nThe perimeter of the rectangle is: %f ", por);

printf("\n\nThe area of the Circle with radius %f is: %f ", radius, aoc);

printf("\nThe circumference of the same circle is: %f", coc);

**}**

The circumference of a circle is same as the perimeter that is the distance around the outer edge.

The formula of circumference is = 2 pi r (pi's symbol)

where r = the radius of the circle

and pi = 3.14(Approx)
