Table 15. Diameters, Areas, And Circumferences Of Circles

Table 15 Diameters Areas And Circumferences Of Cir 131

To find the circumference and area of any diameter greater than any in the preceding table. Rule. - Multiply any diameter given above by the factor 2, 3, 4, or 5, etc., the product of which will be the diameter whose circumference and area are wanted. Example. - What is the circumference of 140? Tabular diameter of 35 X 4 = 140. Tabular circumference of 35 = 109.9 X 4 = 439.6, circumference wanted. Rule for the Area. - Multiply the tabular area of tabular diameter by the square of the factor. Example. - What is the area of 140? Tabular area of 35 = 962.11 X 16 (is the square of the factor 4) = 15,393.76, area wanted. The Circle. - The circumference of a circle is equal to the diameter multiplied by 3.1416. The area of a circle is equal to the square of the diameter multiplied by .7854.
