Formula & Methodology
The formula for the surface area of a cylinder is:
Surface Area = 2 * π * r * (r + h)
where r is the radius and h is the height.
Real-World Examples
Example 1
A cylinder has a radius of 5 cm and a height of 10 cm. The surface area is:
2 * π * 5 * (5 + 10) = 314.16 cm²
Example 2
A cylinder has a radius of 3 cm and a height of 8 cm. The surface area is:
2 * π * 3 * (3 + 8) = 226.19 cm²
Example 3
A cylinder has a radius of 7 cm and a height of 15 cm. The surface area is:
2 * π * 7 * (7 + 15) = 565.49 cm²
