Easily determine the volume of a frustum of a right circular cone with our free online calculator. Input the radii of the top and base, along with the height, to get instant, accurate results. Ideal for academic studies, engineering projects, and design work requiring precise geometric calculations.
Formula:
The formula to calculate the volume of a frustum of a right circular cone is:
V = (1/3)πh(R² + Rr + r²)
- V = Volume of the frustum
- π = Pi (approximately 3.14159)
- h = Height of the frustum
- R = Radius of the base (larger circle)
- r = Radius of the top (smaller circle)
Ensure R >= r for standard frustums, and h > 0. The formula handles R < r correctly for inverted forms.
