🔍How to Calculate Cone Volume
🔺 Understanding Cone Volume
A cone is a 3D shape with a circular base that tapers to a point (apex). The volume formula V = (1/3)πr²h shows it's one-third the volume of a cylinder with the same base and height.
Essential Formulas:
Volume: V = (1/3)πr²h
Surface Area: SA = πr² + πrl
Slant Height: l = √(r² + h²)

❓Frequently Asked Questions
Why is cone volume one-third of cylinder volume?
Cone volume is exactly 1/3 of a cylinder with the same base and height. This relationship comes from calculus integration.
Cylinder: V = πr²h
Cone: V = (1/3)πr²h
The tapering from full circle to point creates this 1/3 relationship through mathematical integration.
How do I calculate slant height from radius and height?
Slant height uses the Pythagorean theorem, treating radius and height as legs of a right triangle:
Slant Height=√(r² + h²)
This measurement is essential for calculating lateral surface area and material requirements.
