Cone Formulas

V = (1/3)πr²h
Volume of a cone
l = (r² + h²)
Slant height (Pythagorean theorem)
A = πrl
Lateral (curved) surface area
A = πr(r + l)
Total surface area
A = πr²
Base area (circle)
π 3.14159
Pi constant

About Cone Calculations

A cone is a three-dimensional geometric shape with a circular base that tapers smoothly to a point called the apex or vertex. This calculator helps you find all properties of a right circular cone when you know the base radius and height.

Key Properties

  • Radius (r): Distance from center to edge of base
  • Height (h): Perpendicular distance from base to apex
  • Slant Height (l): Distance along the surface from base to apex
  • Volume: Amount of space inside the cone
  • Surface Area: Total area of all surfaces

How to Use

  1. Enter the base radius
  2. Enter the height
  3. Select your preferred unit
  4. All values calculate instantly
  5. Adjust precision as needed
