# Surface Area of a Cylinder

Surface Area of a Cylinder Calculator– a valuable tool for engineers, students, and enthusiasts working with cylindrical structures. This calculator simplifies the process of computing the surface area of a cylinder, providing accurate results for various applications in geometry and engineering.

### What is the Surface Area of a Cylinder Calculator ?

The Surface Area of a Cylinder Calculator is a specialized tool designed to calculate the total surface area of a cylinder. It is particularly useful for individuals working with cylindrical shapes in fields such as architecture, engineering, and mathematics.

### What is the formula of Surface Area of a Cylinder ?

The calculator employs the following formula for computing the surface area (A) of a cylinder:

`A = 2πr2 + 2πrh`

Where:

• r is the radius of the cylinder,
• h is the height of the cylinder,
• π is the mathematical constant pi (approximately 3.14159).

This formula takes into account the lateral surface area and the area of the two circular bases.

Example 1:

Given Radius (r): 4 units, Height (h): 8 units

Using the formula: `A = 2πr2 + 2πrh`

A = `2π×42 + 2π×4×8`

Area = 200.96 units2

Example 2:

Given Radius (r): 5 units, Height (h): 12 units

Using the formula: `A = 2πr2 + 2πrh`

A = `2π×52 + 2π×5×12`

Area = 376.99 units2

Example 3:

Given Radius (r): 3 units Height (h): 10 units

Using the formula: `A = 2πr2 + 2πrh`

A = `2π×32 + 2π×3×10`

Area = 188.50 units2

## Frequently Asked Questions
