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.

To find the curved surface area of the wire, we will follow these steps: ### Step 1: Calculate the Least Count of the Screw Gauge The least count (LC) of the screw gauge can be calculated using the formula: \[ \text{Least Count} = \frac{\text{Pitch}}{\text{Number of divisions on the circular scale}} \] Given: - Pitch = 1 mm = 0.1 cm (since we need the answer in cm²) ...
