Cone Volume & Surface Area
Calculate the volume, lateral surface area, and total surface area of a circular cone.
Geometry of a Cone
A cone is a three-dimensional shape that tapers smoothly from a flat, circular base to a point called the apex or vertex.
Volume vs Surface Area
- Volume: The amount of space inside the cone. It is exactly one-third the volume of a cylinder with the same base and height.
V = ⅓πr²h - Surface Area: The total area of the outside surfaces, including the circular base and the curved lateral face.
Frequently Asked Questions
What is the slant height?
The slant height is the distance from the edge of the circular base up the side of the cone to the apex. It forms the hypotenuse of a right triangle with the radius and the vertical height.
