Precision Geometry: Cylinder Surface Area Calculator
Calculating the surface area of a cylinder involves finding the area of the two circular bases plus the area of the curved side (the lateral area). Whether you are an engineering student or a homeowner calculating materials for a project, our Free Cylinder Surface Area Calculator provides high-precision results instantly.
The Mathematical Formula
To find the total surface area (A), the tool combines the area of the top and bottom circles with the rectangular area of the side if it were "unrolled." The formula is:
Where:
- r is the radius of the base.
- h is the height of the cylinder.
- π (pi) is approximately 3.14159.
