The pitch of a screw gauge is 1 mm and there are 100 division on the circular scale. While measuring the diameter of a wire, the linear scale reads 1mm and 47th division on circular scale coincides with the reference line. The length of the wire is 5.6 cm. Find the curved surface area `(in cm^2)` of the wire in proper significant figures.

Text Solution

Verified by Experts

The correct Answer is:
`2.6cm^(2)` (in two significant figures)
