The length of a cylinder is measured with a meter rod having least count `0.1 cm`. Its diameter is measured with Vernier calipers having least count `0.01 cm`. Given that length is `5.0 cm` and radius is ` 2 cm`. Find the percentage error in the calculated value of the volume.

Answer

3

Explanation

`V=pir^(2)h=(piD^(2)h)/(4)rArr (Delta V)/(V)=(2 Delta D)/(D)+(Delta h)/(h).(Delta V)/(V)xx 100 =[2 xx((0.01)/(2.00))+((0.1)/(5.0))] xx 100 =3%`.
