Program to find the surface area of the cylinder

Explanation

In this program, we have a cylinder with the given radius and height. We need to find its Surface area.

A cylinder is a three-dimensional geometrical figure/container with straight parallel sides and two circular cross-sections. So we have three surfaces of the cylinder.

The surface area of two circular cross-sections = 2( Π × r × r )

The surface area of parallel sides = Circumference times the height = 2 Π × r × h

Total Surface Area of Cylinder = 2( Π × r × r ) + 2 Π × r × h = 2 Π (r + h)

Formula

Surface Area of Cylinder = 2 Π  (r + h)  Here, r is the radius and h is the height of the cylinder.  Π ( pi ) = 22/7 = 3.14

Algorithm

Define the values of radius and height.
Insert into given formula.
Print the Surface Area of Cylinder.

Complexity

O(1)

Solution

Python

  r = 2.0  #radius  h = 5.0 #height  surfacearea = (2*22*(r + h))/7 #calculation  print (“Surface Area Of Cylinder : “);  print (surfacearea); #prints surface area  

Output:

Surface Area Of Cylinder :   44.0

C

  #include<stdio.h>  int main()     {       float r,  h, surfacearea;      r=2.0;       h = 5.0;      surfacearea = (2*22*(r + h))/7;      printf(“nn Surface Area of Cylinder is : %f”, surfacearea);      return (0);     }  

Output:

Surface Area of Cylinder is: 44.00000

JAVA

              public class test              {               public static void main(String args[])              {               float r, h, surfacearea;                r = 2;                h  = 5;                surfacearea = (22*r*(r+h))/7;                System.out.println(“Surface Area of Cylinder is: “+surfacearea);              }              }  

Output:

Surface Area of Cylinder is:  44.000000

C#

  using System;  class Program  {      static void Main()       {          float r, h, surfacearea;          r  = 2;          h = 5;           surfacearea = (22*r*(r+h))/7;          Console.WriteLine(“Surface Area of Cylinder is:”+surfacearea);      }  }  

Output:

Surface Area of Cylinder is:  44

PHP

  <?php  $r = 2.0;  $h =  5.0;  $surfacearea =(22*$r*($r+$h))/7;  echo(“Surface Area Of Cylinder is = “);  echo($surfacearea);  ?>  

Output:

Surface Area Of Cylinder is = 44
