Compute the volume of a cone from radius and height.
Input Data
R
H
Results
Volume = (1/3)πr²h.
37.6991
Explanatory note about the result.
V = (1/3)πr²h = 37.6991；側面積 47.1239；表面積 75.3982。
At a glance:V = (1/3)·π·r²·h. Complements cone and cylinder-volume.
Formula
V = (1/3)·π·r²·h.
How to Use
- Enter radius and height.
- The tool returns the volume.
Case Studies
r=3, h=5
V = (1/3)π·9·5 = 15π ≈ 47.12.
FAQ
Why one third?
A cone is one third of the cylinder with the same base and height (by calculus/Cavalieri).
