Pamphlet, Tables of Circumferences and Areas of Circles

Description
Mathematical tables have often been combined for convenient reference. This anonymous pamphlet includes tables of the circumferences and areas of circles to five places. It goes from a diameter of 1/64 inch to a diameter of 100 inches, advancing by 1/8 of an inch. Also included is a table of squares, cubes, square roots, cube roots, logarithms, reciprocals, circumferences and circular areas for numbers from 1 to 1000. There then is a table of natural sines, cosines, tangents, and cotangents to five places. Finally there is a one-page table of decimal equivalents.
The author and date of the tables is not given. A mark on the cover reads: P RNC-GEN-P220. A mark on the bottom of the last page reads: PRNC-3667-11-20-47-5000. There was a Potomac River Naval Command active in 1940s and 1950s. It administered, among other things, the Washington Naval Gun Factory. George Norton, who owned these tables, worked at the Washington Naval Gun Factory during part of that time.
