Cone Calculator

Enter a cone's base diameter and height. Slant height, surface area, and volume are worked out for you.

Radius
Slant height — √(r² + h²)
Base circumference — π × diameter
Base area — π × r²
Lateral surface area — π × r × slant height
Total surface area — base area + lateral area
Volume — ⅓ × base area × height
