Cone Frustum Volume Calculator
Find right circular cone frustum volume πh(R² + Rr + r²)/3.
Open toolFind a right circular cone slant height as sqrt(radius² + height²). Provide Cone base radius, Perpendicular cone height to compute results directly in your browser. Use the same length unit for every length. Areas use squared units and volumes use cubed units. Right circular cone only, not an oblique cone. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.
Enter the inputs, then select Calculate.
