Slant Height l = √(r² + h²)
Base Area = πr²
Lateral Area = πrl = πr√(r² + h²)
Surface Area = Base Area + Lateral Area = πr² + πrl
Volume = (1/3) × Base Area × Height = (1/3)πr²h
📖 About Cone
A cone is a geometric shape formed by a circular base and a vertex. The line connecting the vertex to the center of the base is perpendicular to the base. Cones are common in daily life, such as ice cream cones, traffic cones, sand piles, etc.
Cone Features:
- Has one circular base
- Has one vertex (apex)
- The distance from the vertex to the center of the base is the height
- The distance from the vertex to any point on the circumference is the slant height
- The volume is one-third of a cylinder with the same base and height
