Cone Volume Calculator
Calculate the volume and surface area of a cone from its radius and height.
Enter radius and height.
Cone Formulas
Volume = ⅓πr²h
Slant height (l) = √(r² + h²)
Lateral surface area = πrl
Total surface area = πr(l + r)
Slant height (l) = √(r² + h²)
Lateral surface area = πrl
Total surface area = πr(l + r)
Example: r = 4, h = 6.
Volume = ⅓ × π × 16 × 6 = 100.53 cubic units
Slant height = √(16 + 36) = √52 ≈ 7.21
Volume = ⅓ × π × 16 × 6 = 100.53 cubic units
Slant height = √(16 + 36) = √52 ≈ 7.21
FAQ
How does cone volume relate to cylinder volume?
