Step-by-step explanation:
A cylinder is a solid which has a uniform, circular cross-section.
Curved surface area of a cylinder = 2 π r h. ...
Total surface area of a cylinder = 2 π r h + 2 π r2 ...
Curved surface area of a hollow cylinder = 2 π R h + 2 π r h. ...
Total surface area of a hollow cylinder = 2 π R h + 2 π r h + 2 (π R2 − π r2)
