A) 2%, 4% and 4 %
B) 6%, 4% and 2%
C) 6%, 6% and 6%
D) 2%, 4% and 6%
Correct Answer: D
Solution :
\[\because \] \[D=2R\]\[\therefore \] \[\frac{\Delta D}{D}\times 100=\frac{\Delta R}{R}\times 100=2%\] \[\because \]\[A=4\pi {{R}^{2}}\]\[\therefore \]\[\frac{\Delta A}{A}\times 100=2\frac{\Delta R}{R}\times 100=4%\] \[\because \]\[V=\frac{4}{3}\pi {{R}^{3}}\]\[\therefore \]\[\frac{\Delta V}{V}\times 100=3\frac{\Delta R}{R}\times 100=6%\]You need to login to perform this action.
