IM 7.3.3 Practice: Exploring Circumference
Diego measured the diameter and circumference of several circular objects and recorded his measurements in the table.
One of his measurements is inaccurate. Which measurement is it? Explain how you know.
Complete the table. Use one of the approximate values for pi discussed in class (for example 3.14, 22/7, 3.1416).
Explain or show your reasoning for how you determined the missing values in the table.
is the center of the circle, and the length of is 15 centimeters.
Name a segment that is a radius. How long is it?
Name a segment that is a diameter. How long is it?
Consider the equation y=1.5x +2 . Find four pairs of x and y values that make the equation true. Plot the points (x,y) on the coordinate plane.
Based on the graph, can this be a proportional relationship? Why or why not?
