Area Of Cylinder Calculator

A cylinder is one of the most common 3D geometric shapes used in mathematics, engineering, construction, and manufacturing. From water tanks and pipes to cans and industrial containers, cylinders are everywhere. To design or analyze them, it is important to calculate their surface area, which includes both curved and flat circular surfaces.

Our Area of Cylinder Calculator helps you quickly find the total surface area, curved surface area (lateral area), and base area of a cylinder using simple inputs: radius and height.


What Is an Area of Cylinder Calculator?

An Area of Cylinder Calculator is a geometry tool used to calculate:

  • Total Surface Area of a cylinder
  • Curved (lateral) Surface Area
  • Area of circular bases

It simplifies complex formulas and gives instant results for students, engineers, architects, and designers.


How Does the Area of Cylinder Calculator Work?

The calculator uses standard geometry formulas based on radius and height.

Required Inputs

  • Radius (r) of the base
  • Height (h) of the cylinder

Formulas Used

1. Curved Surface Area (CSA)

CSA = 2πrh

2. Area of Both Bases

Base Area = 2πr²

3. Total Surface Area (TSA)

TSA = 2πr(h + r)


Example Calculation

Suppose:

  • Radius (r) = 5 cm
  • Height (h) = 10 cm

Step 1: Curved Surface Area

2πrh = 2 × 3.1416 × 5 × 10 = 314.16 cm²

Step 2: Base Area

2πr² = 2 × 3.1416 × 25 = 157.08 cm²

Step 3: Total Surface Area

314.16 + 157.08 = 471.24 cm²
