The formula to calculate the total surface area of a hollow cylinder is:
\[ \text{TSA} = 2\pi (r_{\text{inner}} + r_{\text{outer}}) (r_{\text{outer}} - r_{\text{inner}} + h) \]
Where:
The total surface area of a hollow cylinder is the total area covered by the inner and outer surfaces, including the top and bottom surfaces.
Let's assume the following values:
Using the formula:
\[ \text{TSA} = 2\pi (6 + 10) (10 - 6 + 8) \approx 1206.37 \, \text{square meters} \]
The total surface area is approximately 1206.37 square meters.
| Inner Radius (meters) | Outer Radius (meters) | Height (meters) | Total Surface Area (square meters) |
|---|---|---|---|
| 6 | 10 | 8 | 1,206.3716 |
| 5 | 12 | 10 | 1,815.8406 |
| 7 | 14 | 12 | 2,506.9909 |
