The length of a cylinder is measured with a metre rod having least count 0.1cm. Its diameter is measured with vernier callipers having least count 0.01 cm. Given the length is 5.0cm, and radius is 2.00 cm. the percentage error in the calculated value of volume will be-

A

`2% `

B

`1%`

C

`3%`

D

`4%`

Text Solution

Verified by Experts

The correct Answer is:
C

`because V = (piD^(2) l)/(4)`
`therefore (DeltaV)/(V) = (2 Delta D)/(D) + (Deltal)/(l) = ((2(0.01))/(4) + (0.1)/(5)) xx 100`
`" "2.5%` (Approx)
