The Program in C++ to Calculate the Volume of a cylinder is given below:
#include <iostream>
#include <cmath>
using namespace std;
int main() {
double radius, height, volume;
cout << "Enter the radius of the cylinder: ";
cin >> radius;
cout << "Enter the height of the cylinder: ";
cin >> height;
volume = M_PI * pow(radius, 2) * height;
cout << "Volume of the cylinder: " << volume << endl;
return 0;
}
Output:
Enter the radius of the cylinder: 5
Enter the height of the cylinder: 4
Volume of the cylinder: 314.159
Pro-Tips💡
In this program, the user is prompted to enter the radius and height of the cylinder.
These values are then stored in the corresponding variables.
The volume of the cylinder is calculated using the formula ‘volume = M_PI * pow(radius, 2) * height ‘.
The resulting volume of the cylinder is then displayed on the screen.
Note: M_PI is a predefined constant in C++ for pi (3.14159265358979323846)
Also, ‘pow(x, y)‘ is a library function in C++ that returns the value of x raised to the power of y.
