Calculate concrete for round piers or footings.
Each round footing is a cylinder, so its volume is pi times the squared radius times the height. Multiplying by the count gives the total concrete in cubic yards. Round piers for decks and posts need their own volume check so you order the right concrete and dig to the right depth.
Footing Concrete
Volume = pi x (diameter/2)^2 x height

This calculator takes 3 inputs: Diameter, Height, Number of footings. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
