About Cone Calculator
The Cone Volume Calculator finds the cubic capacity of a right circular cone. The formula for the volume of a cone is exactly one-third the volume of a cylinder with the same base and height.
How Cone Calculator Works
- Step 1: Radius & Height: Input the radius of the cone's circular flat base and the straight vertical height to the tip (apex).
- Step 2: Calculate: The algorithm evaluates ⅓πr²h instantly.
Frequently Asked Questions
Is height the same as slant length?
No! The height must be the straight perpendicular line from the center of the base to the top point. Slant length is the distance along the outside surface.
Does this work for slanted (oblique) cones?
Yes. The volume formula works for oblique cones as long as the height is the perpendicular distance from the base plane to the apex.
What is a frustum?
A frustum is a cone with the top chopped off. This calculator only works for complete, pointed cones.
