. The pitch of a screw gauge is $$1 \ mm$$ and there are $$100$$ divisions on the circular scale. While measuring the diameter of a wire, the linear scale reads $$1$$ mm and $$47^{th}$$ division on the 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 appropriate number of significant figures assuming there is no zero error in the instrument
