1000 Things Worth Knowing by Nathaniel C. Fowler, Jr. Section measurements. Diameter of a circle times 3.1416 equals circumference. Radius of a circle times 6.283185 equals circumference. Square of the radius of a circle times 3.1416 equals area.
Square of the diameter of a circle times 0.7854 equals area. Square of the circumference of a circle times 0.07958 equals area. Half the circumference of a circle times half its diameter equals area. Circumference of a circle times 0.159155 equals radius. Square root of the area of a circle times 0.56419 equals radius.
Circumference of a circle times 31831 equals diameter. Square root of the area of a circle times 1.12839 equals diameter. Diameter of a circle times 0.86 equals side of inscribed equilateral triangle. Diameter of a circle times 0.7071 equals side of an inscribed square. Circumference of a circle times 0.226 equals side of an inscribed square.
Circumference of a circle times 0.282 equals side of square of equal area. Diameter of a circle times 0.8862 equals side of a square of equal area. Base of a triangle times one half the altitude equals area. The product of both diameters times 0.7854 equals area of an ellipse. Surface of a sphere times one sixth of its diameter equals solidity.
Circumference of a sphere times its diameter equals surface. Square of the circumference of a sphere times 0.3183 equals surface. Square root of the surface of a sphere times 1.772454 equals circumference. Square of one of its sides times six equals surface of a cube. Area of the base of a square, round, or triangular pyramid, or of a cone, times one third of
its altitude equals solidity. Area of square times 0.7854 equals area of largest circle within it. Area of circle times 0.625 equals area of largest square within it. Spheres. Square of circumference times 0.3183 equals surface of sphere.
Square of diameter times 3.1416 equals surface of sphere. Square root of surface times 0.5642 equals diameter of sphere. Cube of diameter times 0.5236 equals solidity of sphere. Cube of circumference times 0.0169 equals solidity of sphere. Cube root of solidity times 1.2407 equals diameter of sphere.
Diameter of sphere times 0.5774 equals side of inscribed cube. Square root of solidity times 0.2821 equals radius. Square root of solidity times 1.7725 equals circumference. Cube of radius times 4.1888 equals solidity. Cube root of solidity times 0.6204 equals radius.
Cube root of solidity times 3.8978 equals circumference. Communism and Socialism. Communism is a doctrine which would abolish individual rights, including the ownership of property. It began in England and France but has never made any great progress.
Socialism is allied to communism but is a milder form. It does not suggest the abolition of individual rights but to make all rights subordinate to the good of the people. An acceptable definition of either has never been presented, and members of both parties differ materially.
Socialism, however, has grown very rapidly, and the Socialistic Party in the United States is frequently successful. Some of our ablest scholars and investigators believe that Socialism will become prevalent and that in it is vested many of the solutions to our economic problems. End of Section 9.
