Answer:
The percent of error in her measurement is 1.3%
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
where
D is the diameter
we have
[tex]D=5\ in[/tex]
assume
[tex]\pi=3.14[/tex]
substitute
[tex]C=(3.14)(5)=15.7\ in[/tex] ----> This value represent the 100% (theoretical value)
Find the difference between the theoretical value and the measured value
[tex]15.7-15.5=0.2\ in[/tex]
Find the percentage by proportion
[tex]15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%[/tex]
