(i.e., multiply the diameter by itself), then multiply the result by 3.1416. Divide
the result by 4, then multiply by depth.

Example: Find the cubical content of a vessel 4 feet in diameter by 3 feet
in depth.

(4X4)X3.1416x3

^-----J---------------=37.6992 square feet

To find the number of gallons proceed as for a square or rectangular vessel
(see previous examples).

To find the nominal comparative number of pounds in kilos: Multiply the
number of pounds by 454 and divide by 1000. The result is the number of kilos.

Vice versa: Multiply the number of kilos by 1000 and divide by 454. The
result is the number of pounds.
