CIRCUMFERENCES AND AREAS OF CIRCLES SQUARES, CUBES, SQUARE ROOTS, CUBE ROOTS

If n the radius of the circle, the circumference = 2 πn.
If n = the radius of the circle, the area

= πn2.

On this page the logarithms of integers from 1 to 100 are given in full, with characteristics as well as mantissas. On account of the great differences between the successive mantissas, interpolation cannot safely be employed on this page.

In the remainder of the table only the mantissas are given.

In general, an error of one unit may appear in the last figure of any interpolated value.

Table III is to be used when accuracy is required to more than four figures in the results. In general, the results will be accurate to five figures.
