Python Math: Calculate surface volume and area of a cylinder
Python Math: Exercise-5 with Solution
Write a Python program to calculate surface volume and area of a cylinder.
Note: A cylinder is one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given straight line, the axis of the cylinder.
Sample Solution:-
Python Code:
pi=22/7
height = float(input('Height of cylinder: '))
radian = float(input('Radius of cylinder: '))
volume = pi * radian * radian * height
sur_area = ((2*pi*radian) * height) + ((pi*radian**2)*2)
print("Volume is: ", volume)
print("Surface Area is: ", sur_area)
Sample Output:
Height of cylinder: 4 Radius of cylinder: 6 Volume is: 452.57142857142856 Surface Area is: 377.1428571428571

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
