Quarter Circle Area Calculator

How to Use

1. Enter the radius of the circle in the input field.
2. Click the "Calculate" button to compute the area of the quarter circle.
3. The result will be displayed in the area field.
4. Click "Reset" to clear all inputs and results.

Understanding the Formula

The area of a quarter circle is calculated using the formula:

Area = (π * r²) / 4

This formula calculates the area of a full circle (π * r²) and then divides it by 4 to get the area of a quarter circle.

Applications

This calculator can be used in various fields including:

• Architecture and construction for planning quarter circular windows or arches
• Landscaping for designing quarter circular flower beds
• Engineering for calculating areas in mechanical designs
• Mathematics education for teaching circle properties
