Graph Diameter vs. Circumference



Calculations

% error = | Experimental Value - True Value |/ True Value x 100

Experimental Value = Slope of line True Value = 3.1415

Questions

1. Use your graph to interpotate (inside the graph)the circumference of a circle that has a diameter of 6.0 cm.

2. Use your graph to extrapotate (outside the graph) the diameter of a circle that has a circumference of 75 cm.

3. Is Pi some random number or is it related to something?
