Curved surface area of a Hollow Cylinder (Pipe)
CSA = 2πh(R + r)
Where: CSA = Curved surface area, R = outer radius, 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: CSA_ (Curved surface area)
- Formula: CSA = 2·π·h·(R + r)
- Substitute the values: CSA = 2·π·5·(10 + 7)
- Result: CSA = 534.070751
Answer: CSA_ = 534.070751
