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.
