Frequently Asked Questions
What is the cone volume formula?
Volume = (1/3)πr²h. A cone is exactly one-third the volume of a cylinder with the same base and height.
Does the slant height matter?
No — the formula uses the vertical (perpendicular) height, not the slant height.
Can I calculate a truncated cone?
For a truncated cone (frustum), calculate the full cone volume and subtract the removed top portion.
