Cone Volume Calculator
Find the volume of a cone from its base radius and height.
Volume84.82units³
Slant height9.49units
Volume = π·r²·h ÷ 3 — exactly one third of a cylinder with the same base and height. The slant height is √(r² + h²). With r = 3, h = 9: volume ≈ 84.82.
Questions
How do I calculate the volume of a cone?
Multiply π by the radius squared by the height, then divide by 3: Volume = π·r²·h ÷ 3. A cone is one third of the cylinder that contains it.
