PROBL. VI. How to Measure a Cylinder Vessel.
SUppose the Diameter of the Head AB be 24 Inches, and the length thereof AC be 30 Inches, To find the contents in Ale-Gallons.* 1.1 Extend the Compasses always from the Gage-point, which for Ale is 18 95/100 Inches unto the diameter 24 Inches; the same distance will reach from the length 30 Inches turned twice over unto 48 13/190 Gal∣lons.
For Wine.
Extend the Compasses from the Gage-point 17 15/100 unto the diameter 24; the same distance will reach from 30 turned twice to 58 7/10 Gallons.
The Arithmetical way.
For Ale. ABqXAC / 359 = Ale-Gallons (viz.) 48 13/190
For Wine. ABqXAC / 294 = Wine-Gallons, (viz.) 58 75/100
