Volume of Solid of Revolution/Historical Note

Theorem
The technique of finding the Volume of Solid of Revolution by dividing up the solid of revolution into many thin disks and approximating them to cylinders was devised by sometime around or after $1612$, reportedly on the occasion of his wedding in $1613$.

His inspiration was in the problem of finding the volume of wine barrels accurately.

He published his technique in his $1615$ work (New Stereometry of Wine Barrels).
