Given diameter and height, find the perimeter of a cylinder.
Perimeter is the length of the outline of a two – dimensional shape. A cylinder is a three – dimensional shape. So, technically we cannot find the perimeter of a cylinder but we can find the perimeter of the cross-section of the cylinder. This can be done by creating the projection on its base, thus, creating the projection on its side, then the shape would be reduced to a rectangle.
Formula :
Perimeter of cylinder ( P ) = 
here d is the diameter of the cylinder
h is the height of the cylinder
Examples :
Input : diameter = 5, height = 10 Output : Perimeter = 30 Input : diameter = 50, height = 150 Output : Perimeter = 400
CPP
// CPP program to find// perimeter of cylinder#include <iostream>using namespace std;// Function to calculate perimeterint perimeter(int diameter, int height){ return 2 * (diameter + height);}// Driver functionint main(){ int diameter = 5; int height = 10; cout << "Perimeter = "; cout<< perimeter(diameter, height); cout<<" units\n"; return 0;} |
Output :
Perimeter = 30 units
Time Complexity: O(1)
Auxiliary Space: O(1)
