If the error in measuring diameter of a circle is 4%, the error in the circumference of the circle will be ?

Answers (1)

As we learnt in 

Percentage error in the value of x -

\dpi{100} x= \frac{\left ( \Delta a+\Delta b \right )}{a+b}\times 100\%

- wherein

\Delta a= absolute error in measurement of a

\Delta b= absolute error in measurement of b

\Delta x= absolute error in measurement of x

 

 D\propto r  therefore there will be no change in error, it will remain 4% for radius also.
