Exploring the Relationship Between Circumference and Diameter in 8MAA and 8MAB
In recent mathematics lessons, students in 8MAA and 8MAB embarked on an exciting investigation into one of geometry's fundamental relationships: the connection between the circumference of a circle and its diameter. This hands-on activity allowed students to explore this relationship using simple tools like string and various circular objects.
Students were provided with different circular items such as plates, coasters, cans and cups. They were tasked with measuring the circumference of each object using a piece of string. After carefully wrapping the string around the object's edge, they straightened it out and measured its length using a tape measure. They then measured the diameter of each object, ensuring accuracy by measuring through the center of the circle.
As students compared the measurements of the circumference and the diameter, they began to notice a consistent pattern. By dividing the circumference by the diameter for each object, they discovered that the ratio was always approximately the same—around 3.14. This magical number is none other than Pi (π), a constant that is crucial in the study of circles.
