As we learned,

The 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.
