What is the relationship between the diameter and the circumference of a circle?
Question # 1
Using the simulation tool, determine the respective circumferences corresponding to circles with diameters 3.1, 4.8, and 9.6 cm.
Question #2
Based on the preceeding question, calculate the ratio πΆ/π for each measurement. The ratio C/d is equal to--------.
3.14
Question # 3
Knowing that π = 3.14, choose the equation that relates the circumference of a circle to its diameter.
Question #4
Calculate the circumference of a circle of radius 2.4 cm.
Question #5
A Grade 7 student measured the diameter and the circumference of a wheel.[br][br]Suggest a method, using calculation, to check whether the studentβs measurements are valid.
If the ratio of C/d is equal to 3.14, then the measurements are valid
