A thin wire has length of 21.7 cm and radius 0.46 mm. Calculate the volume of the wire to correct significant figures?

A

`4cm^(3)`

B

`0.14 cm^(3)`

C

`0.14 cm^(3)`

D

`0.001 cm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Given,` "l"=21.7cm, r=0.46mm=0.0046cm`
Volume of wire, `V=pir^(2)l=(22)/(7)(0.046)^(2)(21.7)`
` =0.1443cm^(3)=0.14cm^(3)`
