Measuring Circumference and Diameter -SMEC

Using the simulation tool, determine the respective circumferences corresponding to circles with diameters 3.1, 4.8, and 9.6 cm.

Based on the preceeding question, calculate the ratio 𝐶/𝑑 for each measurement. The ratio C/d is equal to--------.

Knowing that 𝜋 = 3.14, choose the equation that relates the circumference of a circle to its diameter.

Calculate the circumference of a circle of radius 2.4 cm.
