Finding the Value of Pi

Purpos© To expenmentally determine the value of pa by

1. usłng the averagę crcumference and diameter measurements of a circular ptete 2 analyz^{1 2}tg a graph of circumference vs. diameter measurements for several carcles

Background

•    Pi (²) represonts the ratio between the circumference (C) and the diamoter (d) of a orcie. Th²s relatonship can be written as:

C = xd

•    Pi has an acccptod value of 3.1416.

Materials:

meter stlck    strtng    circular piąte

ruier    scissors    vańou$ circiMar objocts

Procedur©:

Part 1:

1 Have each member of the lab group measure the diameter of the c²cular piąte (We d»d thts by roughly estimaling v\ticrc the widest part of the piąte was placing a string across that dtstance. then measuhng the length of the string with a rui er.)¹

2.    Have each member measure the crcumference o# the circular piąte. (We d»d th»s by wrapping the string one fuli tum around the outsidc Of the piąte, then measuring the length of the string with a ruler)

Part 2:

3.    Have each group member find one additional orcular object and measure the diameter and circumference of that object. (We used the same measuring proccss outlined in pad 1 )

Data and Calculations:
