C Program to Find Volume and Surface Area of Cylinder

«
»

This is a C Program to find the volume and surface area of cylinder.

Problem Description

This C Program calculates volume and surface area of cylinder.

Problem Solution

The formula used in this program Surface_area = 2 * Pi * r * (r + h), Volume = Pi * r * r * h where Pi = 22/7.

Program/Source Code

Here is source code of the C Program to Find the volume and surface area of cylinder.The C program is successfully compiled and run on a Linux system. The program output is also shown below.

/*
 * C Program to Find the Volume and Surface Area of cylinder
 */
#include <stdio.h>
#include <math.h>
 
int main()
{
 
    float radius, height;
    float surface_area, volume;
 
    printf("Enter  value for  radius and height of a cylinder : \n");
    scanf("%f%f", &radius, &height);
    surface_area = 2 * (22 / 7) * radius * (radius + height);
    volume = (22 / 7) * radius * radius * height;
    printf("Surface area of cylinder is: %.3f", surface_area);
    printf("\n Volume of cylinder is : %.3f", volume);
    return 0;
}
Program Explanation

In this C program, library function defined in <math.h> header file is used to compute mathematical functions. We are reading the radius and height of a cylinder using ‘radius’ and ‘height’ variables respectively. To find the surface area and volume of a cylinder, the following formulas are used.
Surface area = 2 * (22 / 7) * radius * (radius + height)
Volume = (22 / 7) * radius * radius * height
