What Is the Geometry Calculator?

The Geometry Calculator is an interactive tool that helps you calculate properties of both 2D and 3D geometric shapes. Whether you need to find the area of a triangle, the volume of a cone, or the perimeter of a rectangle, this tool provides quick, accurate results along with step-by-step formula explanations.

Key Features

  • Supports multiple shapes: square, rectangle, triangle, circle, cube, cylinder, cone, sphere, and more.
  • Calculates key properties such as area, perimeter, volume, surface area, and diagonal lengths.
  • Option to show formulas and calculation steps for educational clarity.
  • Visual diagram display to help understand each shape's dimensions.
  • Precision control with adjustable decimal places.

How to Use the Calculator

Using the Geometry Calculator is simple. Here's how to get started:

  • Step 1: Select a shape from the dropdown menu (e.g., Square, Triangle, Cylinder).
  • Step 2: Enter the required dimensions in the input fields (e.g., side length, radius, height).
  • Step 3: Choose how many decimal places you want in the results.
  • Step 4: (Optional) Check the “Show formulas” box to see step-by-step calculations.
  • Step 5: Click the “Calculate” button to view your results.

Formula Reference

Square: Area = side², Perimeter = 4 × side
Rectangle: Area = length × width, Perimeter = 2 × (length + width)
Circle: Area = π × radius², Circumference = 2 × π × radius
Triangle: Area = √(s × (s − a) × (s − b) × (s − c)), s = semi-perimeter
Cylinder: Volume = π × r² × h, Surface Area = 2πr(h + r)
Cube: Volume = side³, Surface Area = 6 × side²
Sphere: Volume = (4/3)πr³, Surface Area = 4πr²
Cone: Volume = (1/3)πr²h, Surface Area = πr(l + r), l = slant height

Who Can Benefit from This Tool?

This tool is ideal for:

  • Students learning geometry or trigonometry
  • Teachers creating examples and exercises
  • Professionals in architecture, engineering, and design
  • DIY enthusiasts working on projects that involve measuring space or volume
