367473 Assertion :
If percentage error in measuring radius of a sphere is \(\pm 1 \%\), the error in its volume would be \(\pm 3 \%\).
Reason :
\(\dfrac{\Delta V}{V}=3\left(\dfrac{\Delta r}{r}\right)\)

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
