Curved surface area of a Cylinder
CSA = 2πrh
Where: CSA = Curved surface area, h = height, r = radius of the base
Use the same units for all lengths (e.g. all in cm); areas come out in cm², volumes in cm³.
Solved example
Given: h = 7, r = 5
Find: CSA_ (Curved surface area)
- Formula: CSA = 2·π·h·r
- Substitute the values: CSA = 2·π·5·7
- Result: CSA = 219.911486
Answer: CSA_ = 219.911486
