Title : Graphing A oversea telegramar Relationship Objective : To verify the rakear relationship between the electrical circuit and the diam of circular inclinations by taking experimental info and utilizing lifelike techniques. Introduction : parallel of latitude relationship is a statistical term used to withdraw the relationship between a variable star and a constant. running(a) relationships rear end be expressed in a graphical format where the variable and the constant are attached via a straight line or in a mathematical format where the free lance variable is multiplied by the be given coefficient, added by a constant, which determines the dependent variable. How is the electrical circuit of a set cogitate to the diameter? The relationship is true to be C = ?D, where C is the circuit of the circle, D is the diameter of the circle, and ? is the constant pi = 3.141593. Thus, the circumference and the diameter should be straight off proportional. A mend of C against D should yield a line of list ?. Hence, in the experiment, y ? x . The symmetry Pi = C/D endure be compute and compared to the accepted pry of ? = 3.141593. The mensural and accepted values can be compared by cypher the percentage of error using the formula beneath: .

% phantasm = |Pi- ?|/?*100% The values C and D can excessively be compared by plotting C against D (C on the straight and D on the horizontal). If the info follows the equation C = ?D, because the plot will be a line of pitch ? and y-intercept 0. Conclusion : Circumference of a circular object increases linearly with its diameter. The ratio of circumference to diameter is the value of ? = 3.142. The documentary is accepted. References : Books : * Steve Adams and Jonathan Allday, 2000. advanced(a) Physics.
