About this calculator
The Cone Volume Calculator on NumberCals is a free, mobile-friendly tool for anyone needing to calculate volume, surface area, and slant height of a right circular cone. Enter your values in the form below and the result is computed instantly — no sign-up, no installation, no waiting.
Formula used
V = (1/3)π·r²·h; SA = π·r·(r + ℓ); ℓ = √(r² + h²)
What you'll need
- Base Radius (e.g. 3)
- Perpendicular Height (e.g. 8)
What you'll get
- Volume
- Slant Height
- Total Surface Area
- Lateral Surface Area
