Introduction
Calculating the surface area of a hemisphere can be a handy tool for various applications. Whether you’re a student, a math enthusiast, or a web developer, creating an HTML code for a Surface Area of Hemisphere Calculator can be a valuable addition to your skill set. In this guide, we will walk you through the process of building a user-friendly calculator that computes the surface area of a hemisphere based on the radius entered by the user.
How to Use Surface Area Of Hemisphere Calculator
To use the Surface Area of Hemisphere Calculator, follow these simple steps:
- Enter the radius (r) of the hemisphere in the designated input field.
- Click the “Calculate” button.
- The calculator will instantly display the surface area (SA) of the hemisphere.
Formula
The formula used to calculate the surface area of a hemisphere is as follows:
SA = 2πr² + πr²
Where:
- SA represents the Surface Area of the hemisphere.
- r is the radius of the hemisphere.
Example
Let’s say you have a hemisphere with a radius of 5 units. Using the formula, the surface area (SA) can be calculated as:
SA = 2π(5)² + π(5)² SA = 2π(25) + π(25) SA = 50π + 25π SA = 75π square units
So, the surface area of the hemisphere with a radius of 5 units is 75π square units.
FAQs
