A screw gauge having `100` equal division and a pitch of length `1mm` is used to measue the diameter of a wire of length `5.6cm`. The main scale reading is `1mm and 47^(th)` circular division coincides with the scale. Find the curved surface area of wire in `cm^(2)` to appropriate significant fihure.
`(use pi = (22)/(7)`

The circular scale of screw gauge has 100 equal divisions. Its screw pitch is 1 mm. This gauge measures the diameter of a wire of length 5.6 cm. The main scale and the circular scale readings are observed to be 1 mm and 47 respectively. Calculate the area in cm^(2) of the curved surface of the wire keeping the significant figures only.

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