Python

Description : A Python program designed to calculate the manufacturing cost of an open-top cylindrical container. The program takes several inputs including the radius of the container base, the container height, the material cost per square centimeter, and the number of containers to be produced. Using the surface area formula of a cylinder, the program calculates the material cost required to produce one container and the total cost for the entire production batch.

Mathematical Formula Used :

Surface Area = πr² + 2πrh 

Where:

r = radius of the base

h = height of the container

π = pi value (from Python math library) 

Cost per Container = Surface Area × Cost per cm²

Total Cost = Cost per Container × Number of Containers

Features: 

• Input container radius

• Input container height

• Input material cost per square centimeter

• Input number of containers to produce

• Calculate cost per container

• Calculate total production cos 

Description : A Python-based application that calculates a student's Grade Point Average (GPA) based on the grades obtained in multiple courses.

The program allows users to input the number of courses, course names, and numerical scores. It automatically converts the scores into letter grades and grade points, then calculates the final GPA. 

This program helps simulate how academic grading systems calculatestudent performance using a standardized grading scale.

Grading System :

Score ≥ 81  → A  (4.0)

Score ≥ 76  → A- (3.7)

Score ≥ 72  → B+ (3.3)

Score ≥ 68  → B  (3.0)

Score ≥ 64  → B- (2.7)

Score ≥ 60  → C+ (2.3)

Score ≥ 56  → C  (2.0)

Score ≥ 41  → D  (1.0)

Score < 41  → E  (0.0)

Formula Used :

GPA = (Total Grade Points) / (Number of Courses)

Features: 

• Input student name

• Input number of courses

• Input course names and scores

• Automatic score-to-grade conversion

• Grade point calculation

• GPA calculation

• Formatted marksheet output

Description : A Python program to simulate the parabolic motion of an object thrown with a certain initial velocity. The program calculates the horizontal distance achieved at various launch angles and determines the angle that results in the maximum distance. This simulation uses the basic equations of parabolic motion and was created using Python.

Formula for horizontal distance:

x = (v₀² / g) sin(2θ)

Where:

v₀ = velocity

g = gravity (9.8 m/s²)

θ = angle of throw

Features: 

• Enter the initial velocity

• Enter the angle increment

• Calculate the horizontal distance for each angle

• Display the table of angles and distances

• Determine the angle with the maximum distance
