Cylinder, Sphere & Cone Volume Calculator
Compute volume and surface area for cylinders, spheres, hemispheres, and cones. Converts volume to gallons (US) and liters.
MATHCompute volume and surface area for the three most common 3D solids: cylinder (V = πr²h), sphere (V = 4/3 πr³), hemisphere, and cone (V = 1/3 πr²h). Also converts the volume to US gallons and liters.
Cylinder SA = 2πr(r + h). Sphere SA = 4πr². Hemisphere SA = 3πr² (flat base + dome). Cone SA = πr(r + √(r² + h²)). Practical applications: tank sizing, pool fill estimates, propane tank capacity, fuel tank volume.
Disclaimer: All measurements must use the same unit. The gallon/liter conversion assumes US gallons (231 in³); UK gallons differ.
