Cylinder Calculator
Calculate volume and surface area of a cylinder for tanks, pipes, and 3D objects.
Enter radius/diameter and height:
Surface Area
471.2389
Volume
785.39816
Cylinder Calculations 🛢️
Input radius and height to compute volume and surface area.
Key Facts
- Volume = π × r² × h
- Surface Area = 2 × π × r × (r + h)
Formulas
- Volume
Volume = π × r² × h- r = radius, h = height. Volume represents space inside the cylinder. - Surface Area
Surface Area = 2 × π × r × (r + h)- Sum of lateral surface area and top/bottom circles.
Applications 🔧
- Calculate liquid capacity for tanks or barrels.
- Determine material needed to wrap or insulate a cylinder.
- Model pipes and silos in design projects.
FAQs
Do I need to include cylinder ends for surface area?
Yes, surface area formula includes both top and bottom circles plus the lateral area.
