5. PROCEDURE 2: Area vs. Radius In this procedure you will produce a nonlinear graph where one variable is related to the second poweof the other. The graph of this relationship will not be a straight line. This is known as a "chrect square" proportion and the graph will curve upward. The relationship between the area of a circle and the radius of the circle can be stated as follows: The area of a circle is proportional to the square of the radius. Written in symbolic notation: A=r R- Area =x x (radio)squareORA=R R RELATIONSHIP 5.1 the area A is in square centimeters (cn7) the radius Rin centimeters it =3.14. 5.2. CALCULATE THE AREAS OF CIRCLES Use relationship 5.1 to calculate the areas of the circles in table 2.1. Multiply it by the square of the radius (R) for each circle in table 2.1. Record the calculated values in the Area (A) column of table 2.1 5.3. CALCULATE THE RATIO of Area to Radius 1. Round off the calculated circumferences to two decimal places. 2. Complete the ratio (A/R) column by dividing the number in the Area (A) column by the number in the same row of the radius (R) column
