Cone volume and surface
Calculate a right circular cone’s volume, slant height and surface areas.
Enter the base radius and vertical height. The tool finds the slant height √(r² + h²), then calculates volume πr²h/3, lateral area πrs and total area including the circular base.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Worked example
Example input
Base radius: 3 Perpendicular height: 4
Example result
{
"volume": 37.6991118431,
"slantHeight": 5,
"lateralArea": 47.1238898038,
"surfaceArea": 75.3982236862
}Limitations and details
Models a right circular cone with positive dimensions; the height input is perpendicular height, not the slant height.
