Python Program to Calculate Surface Area and Volume of a Cylinder

In the previous article, we have discussed Python Program to Check Pronic Number or Not
Cylinder :

A cylinder is a closed geometrical solid shape with two parallel bases joined by a curved surface.
The bases are circular in shape.

The following is the formula for calculating

The area of a cylinder = 2πr(r+h)
The volume of a cylinder = πr²h

where r = radius of the base circle

h = height of the curved surface

Given the radius and height of the cylinder, and the task is to calculate the surface area and volume of the given cylinder.

Examples:

Example 1:

Input:

Given radius = 2.5
Given height = 3.5

Output:

The surface area of a given cylinder = 137.44467859455347
The volume of a given cylinder = 68.72233929727673

Example 2:

Input:

Given radius = 7
Given height = 1.5

Output:

The surface area of a given cylinder = 461.81412007769956
The volume of a given cylinder = 230.90706003884978

Program to Calculate Surface Area and Volume of a Cylinder

Below are the ways to calculate the surface area and volume of the given cylinder.

Using Mathematical Formula (Static Input)
Using Mathematical Formula (User Input)

Method #1: Using Mathematical Formula (Static Input)

Approach:

Import math module using the import keyword.
Give the radius as static input and store it in a variable.
Give the height as static input and store it in another variable.
Calculate the surface area of the given cylinder using the above given mathematical formula, math.pi () method and store it in another variable.
Calculate the volume of the given cylinder using the above given mathematical formula, math.pi () method and store it in another variable.
Print the surface area of the given cylinder.
Print the volume of the given cylinder.
The Exit of the program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the radius as static input and store it in a variable.
gvn_radius = 4
# Give the height as static input and store it in another variable.
gvn_heigt = 7
# Calculate the surface area of the given cylinder using the above given mathematical
# formula, math.pi () method and store it in another variable.
surfc_area = 2*math.pi*pow(gvn_radius, 2)*gvn_heigt
# Calculate the volume of the given cylinder using the above given mathematical formula,
# math.pi () method and store it in another variable.
vol = math.pi*pow(gvn_radius, 2)*gvn_heigt
# Print the surface area of the given cylinder.
print("The surface area of a given cylinder =", surfc_area)
# Print the volume of the given cylinder.
print("The volume of a given cylinder =", vol)

Output:

The surface area of a given cylinder = 703.7167544041137
The volume of a given cylinder = 351.85837720205683

Method #2: Using Mathematical Formula (User Input)

Approach:

Import math module using the import keyword.
Give the radius as user input using the float(input()) function and store it in a variable.
Give the height as user input using the float(input()) function and store it in another variable.
Calculate the surface area of the given cylinder using the above given mathematical formula, math.pi () method and store it in another variable.
Calculate the volume of the given cylinder using the above given mathematical formula, math.pi () method and store it in another variable.
Print the surface area of the given cylinder.
Print the volume of the given cylinder.
The Exit of the program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the radius as user input using the float(input())function and store it in a variable.
gvn_radius = float(input("Enter some random number = "))
# Give the height as user input using the float(input())function store it in another variable.
gvn_heigt = float(input("Enter some random number = "))
# Calculate the surface area of the given cylinder using the above given mathematical
# formula, math.pi () method and store it in another variable.
surfc_area = 2*math.pi*pow(gvn_radius, 2)*gvn_heigt
# Calculate the volume of the given cylinder using the above given mathematical formula,
# math.pi () method and store it in another variable.
vol = math.pi*pow(gvn_radius, 2)*gvn_heigt
# Print the surface area of the given cylinder.
print("The surface area of a given cylinder =", surfc_area)
# Print the volume of the given cylinder.
print("The volume of a given cylinder =", vol)

Output:

Enter some random number = 5.5
Enter some random number = 8
The surface area of a given cylinder = 1520.53084433746
The volume of a given cylinder = 760.26542216873
