C++ Program to find Volume and Surface Area of a Cylinder

Write a C++ Program to Find the Volume and Surface Area of a Cylinder with an example. This C++ program allows user to enter the radius and height of a Cylinder. Next, we calculate the Surface Area, Lateral Surface Area, Top Surface Area, and Volume of a cylinder using mathematical formulas. They are

• C++ Volume of a Cylinder = πr²h
• C++ Top Surface Area of a Cylinder = πr²
• C++ Surface Area of a Cylinder = 2πr² + 2πrh
• C++ Lateral Surface Area of a Cylinder= 2πrh

#include<iostream>
#include <cmath>
using namespace std;

int main()
{
	float cy_Radius, cy_Height, cy_sa, cy_Volume, cy_LSA, cy_TopSA;
	
	cout << "\nPlease Enter the Radius of a Cylinder = ";
	cin >> cy_Radius;
	
	cout << "\nPlease Enter the Height of a Cylinder = ";
	cin >> cy_Height;
	
	cy_sa = 2 * M_PI * cy_Radius * (cy_Radius + cy_Height);
	cy_Volume = M_PI * cy_Radius * cy_Radius * cy_Height;
	cy_LSA = 2 * M_PI * cy_Radius * cy_Height; //cy_LSA= Lateral Surface Area of Cylinder
	cy_TopSA = M_PI * cy_Radius * cy_Radius; // cy_TopSA = Top Surface Area
	
	cout << "\nThe Surface Area of a Cylinder           =  " << cy_sa;
	cout << "\nThe Volume of a Cylinder                 =  " << cy_Volume;
	cout << "\nThe Lateral Surface Area of a Cylinder   =  " << cy_LSA;
	cout << "\nTop or Bottom Surface Area of a Cylinder =  " << cy_TopSA;
		
 	return 0;
