How Cone Frustum Volume Calculator works
Find right circular cone frustum volume πh(R² + Rr + r²)/3.
All lengths must use the same unit. Area uses squared units and volume uses cubed units. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded. Smaller radius cannot exceed the larger radius. Finite real inputs; output uses up to 12 significant digits. Floating-point results may be rounded.
