Due Date: ____________
Procedure:
1. Students will randomly select a formula from science, economics
and other math related fields.
2. Students will create a one page summary of the formula which will
include the following information:
a. A legible representation of the formula.
b. The common name for the formula
c. Explanation of all of the numbers and variables, including
units used for the variables
d. A brief summary of how it was discovered and who got credit
for developing the model.
e. Where it is used in the world today.
f. A picture or graph that represents the model.

Applied Math Project: Formulas
C = πd
Circumference of Circle = pi * diameter
Numbers and Variables:
C = Circumference of the circle, measured in units for distance
( i.e. inches, feet, centimeters, meters, miles, etc. )
d = diameter of the circle, measured in the distance units as the
circumference
π = pi, a constant irrational number that has no units. It represents
the ratio of circumference to diameter of circles. 3.14159. . .
Summary if pi and the formula
The history of pi and the formula for Circumference pre-dates
written history. In 1650 B.C. the Rhind Papyrus of ancient Egypt
references the constant that became pi as 4(8/9)2. Even 3600 years ago,
the approximation was fairly accurate at 3.16049. Over the years the
value of pi became more accurate. British mathematician William Jones
first assigned the constant to the Greek letter π. In 1737, the famous
mathematician Leonard Euler adopted π and it became the standard for
the ratio of circumference to diameter.
Where is it used?
The formula is used wherever circles are used, particularly with
measurement of distances. The wheels of cars and bikes use the
formula to measure distance and speed.
