Work out cone volume instantly with clear inputs, formula shown and shareable results.
A cone holds exactly one third of the cylinder that encloses it, so V = ⅓πr²h. The slant height is √(r² + h²) by Pythagoras on the radius and axis.
Volume
V = ⅓πr²h
Slant height
l = √(r² + h²)
⅓ × π × 16 × 9 = 48π ≈ 150.796447 cubic units.
Yes. For an oblique cone the volume formula still uses the perpendicular height, not the slant length.
