Measuring and Calculating a Mathematical Constant In your science notebooks, write the following heading and answer the bell work question. “Measuring and Calculating a Mathematical Constant” 8/27/2015 Homework: Syllabus due by Friday, “Measuring and Calculating a Mathematical Constant” Worksheet (if not finished during class) BW: 1) What is the difference between the circumference and diameter of a circle? 2) Draw a picture that shows this difference.

Objectives I will learn about the relationship between circumference and diameter and how to express this relationship mathematically and graphically. I will show that I understand this relationship by finding the circumference and diameter of several objects, calculating the ratio of circumference/diameter for these objects, and then plotting the data to observe the trend of a line created by a circumference/diameter ratio.

Circumference The circumference of a circle is the distance around it. Mathematical formula: Circumference = 2*pi*Radius

Diameter The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. Mathematical formula: Diameter = 2*Radius
