The pitch of a screw gauge

15 {~mm}

and there are 100 divisions on the circular scale. While measuring diameter of a thick wire. The pitch scale reads

1 {~mm}

and 63 rad division on the circular scale coincides with the reference. The length of the wire is

5.6 {~cm}

, then which one of the following option is correct?

View answer and explanation

Correct option: B

The volume of the wire is

0.117 {~cm}^3

Option B (The volume of the wire is

0.117 {~cm}^3

) is correct because the volume is calculated correctly using the measured diameter and length of the wire.
