Cylinder Surface Area Calculator

Calculate total surface area of a cylinder

About this calculator

This Cylinder Surface Area Calculator quickly computes the total surface area of a cylinder using its radius and height measurements. The tool applies the mathematical formula 2πr(r+h) to determine the complete surface area, including both circular bases and the curved lateral surface. It's essential for engineers, architects, students, and professionals working with cylindrical objects like pipes, tanks, containers, or architectural columns who need accurate surface area calculations for material estimation, coating requirements, or design specifications.

How to use

Enter the cylinder's radius and height in your preferred units (inches, centimeters, meters, etc.). Click the calculate button to instantly get the total surface area result. The calculator will display the surface area in square units corresponding to your input measurements, showing both the lateral surface area and total surface area.

Frequently asked questions

What is the formula for cylinder surface area?

The total surface area formula is 2πr(r+h), where r is the radius and h is the height. This includes both circular bases and the curved surface.

Do I need to use specific units?

No, you can use any units (inches, centimeters, meters). Just ensure both radius and height use the same unit for accurate results.

What's the difference between lateral and total surface area?

Lateral surface area includes only the curved side (2πrh), while total surface area adds both circular bases (2πr² + 2πrh).
