# Surface Area Of Hemisphere Calculator

Surface Area (SA):

## 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:

1. Enter the radius (r) of the hemisphere in the designated input field.
2. Click the “Calculate” button.
3. 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

1. What units should I use for the radius?

You can use any unit of measurement for the radius (e.g., meters, inches, centimeters) as long as you are consistent throughout the calculation.

2. Can I embed this calculator on my website?

Yes, you can easily embed this calculator on your website by including the provided HTML and script code within your web page.

3. Can I round the result to a specific number of decimal places?

Yes, you can adjust the number of decimal places by modifying the toFixed() method in the JavaScript code.

4. What is the significance of calculating the surface area of a hemisphere?

Calculating the surface area of a hemisphere is useful in various fields, including geometry, engineering, and architecture, to determine the amount of material required for a hemisphere-shaped object.

## Conclusion
