Total surface area of a Hollow Cylinder (Pipe)
TSA = 2πh(R + r) + 2π(R² − r²)
Where: R = outer radius, TSA = Total surface area, h = height, r = inner radius
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: R = 7, h = 5, r = 10
Find: TSA_ (Total surface area)
- Formula: TSA = 2·π·h·(R + r) + 2·π·(R² - r²)
- Substitute the values: TSA = 2·π·5·(10 + 7) + 2·π·(-10² + 7²)
- Result: TSA = 213.6283
Answer: TSA_ = 213.6283
