Use the circle above to collect at least five data points in the data table. [br]Vary the radius of the circle across five trials.[br]For each trial, record the corresponding diameter and circumference in the data table .
Based on the recorded data, complete the table by calculating 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.
A Grade 7 student measured the diameter and the circumference of a wheel.[br][br]Suggest a method, using calculation, to check whether the student’s measurements are valid.
If the ratio of C/d is equal to 3.14, then the measurements are valid
