Cylinder Surface Area Calculator

The Cylinder Surface Area Calculator quickly determines the total surface area of any cylinder. Perfect for students, engineers, and everyday users, it transforms complex geometry formulas into fast, accurate, and easy-to-understand results.

What Is a Cylinder?

A cylinder is a three-dimensional geometric shape with:

• Two parallel circular bases, and
• One curved lateral surface connects the two bases.

A cylinder is defined by two main measurements:

• Radius (r) – the distance from the center of the circular base to its edge.
• Height (h) – the distance between the two circular bases.

Formula for Surface Area of a Cylinder

$$\text{TSA}=2\pi r(r+h)$$

Where:

• $r$ = radius
• $h$ = height
• $\pi$ ≈ 3.14159
