The base of a right circular cylinder has a diameter of 5.00 inches. Sally measured the circumference of the base cylinder and r
LUCKY_DIMON [66]

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

C=\pi D

where

D is the diameter

we have

D=5\ in

assume

\pi=3.14

substitute

C=(3.14)(5)=15.7\ in ----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

15.7-15.5=0.2\ in

Find the percentage by proportion

15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%
