Ex.05 Design a Website for Server Side Processing

Date:5.4.2024

AIM:

To design a website to find surface area of a Right Cylinder in server side.

FORMULA:

Surface Area = 2Πrh + 2Πr²
r --> Radius of Right Cylinder
h --> Height of Right Cylinder

DESIGN STEPS:

Step 1:

Clone the repository from GitHub.

Step 2:

Create Django Admin project.

Step 3:

Create a New App under the Django Admin project.

Step 4:

Create python programs for views and urls to perform server side processing.

Step 5:

Create a HTML file to implement form based input and output.

Step 6:

Publish the website in the given URL.
