Cone Volume Calculator
Calculate volume for a right/oblique cone or a truncated cone (frustum) using radius, height, and top radius inputs.
Use Right / oblique cone mode to compute volume from radius r and height h with V = (1/3) × π × r² × h.
Use Truncated cone mode (frustum) with base radius R, top radius r, and depth h using V = (1/3) × π × h × (R² + Rr + r²).
All dimensions must be positive and the top radius cannot exceed the base radius in frustum mode.
Compute cone volume with modes: Right / oblique cone or Truncated cone (frustum).
