Experiment 2
Measurement and Precision
Objective
To determine the value of
π
from the ratio of the circumference to the diameter of a circle
while properly accounting for uncertainty.
Theory
It has been known since ancient times that the ratio of the circumference of a circle to its
diameter is equal to the transcendental number represented by
π
. That is,
π
=
c
d
The instruments you use to measure this have a limit to their precision. You will have
to estimate to the nearest mark on the scale you use. As a general rule your uncertainty
in a measurement can never be less than
