Cylinder Surface Area Calculator High Precision

How to Use the Calculator

1. Enter the radius (r) of the cylinder in your desired units (e.g., meters, centimeters). Ensure it is a positive number.
2. Enter the height (h) of the cylinder in the same units as the radius. Ensure it is a positive number.
3. Click the "Calculate" button. The calculator will compute the surface area using the formula: A = 2πr(r + h).
4. The result will be displayed in square units corresponding to the units you entered for the radius and height.
5. If you want to start over, click the "Reset" button to clear all input fields.

Understanding the Formula

The surface area of a cylinder consists of three parts:

• Top circular face: πr²
• Bottom circular face: πr²
• Lateral surface area: 2πrh

The total surface area is the sum of these three parts, which simplifies to the formula: A = 2πr(r + h).

Example

Suppose you have a cylinder with a radius of 3 units and a height of 5 units:

Surface Area = 2π × 3 × (3 + 5) = 2π × 3 × 8 = 48π ≈ 150.8 square units
