What is the formula for the volume of a cylinder?

Volume equals pi times the radius squared times the height (V = π · r² · h).

How is the total surface area of a cylinder calculated?

Total surface area equals two times pi times the radius times the sum of the radius and height (A = 2 · π · r · (r + h)).

Can I use this for tank or pipe volume?

Yes. A cylindrical tank or pipe volume is just π · r² · h in consistent units.
