A screw gauge of pitch 1mm has a circular scale divided into 100 divisions. The diameter of a wire is to be measured by above said screw gauge. The main scale reading is 1mm and 47^(th) circular division coincides with main scale. Find the curved surface area of wire in true significant figures. (Given the length of wireis equal to 5.6 cm and there is no zero-error in the screw gauge.)

Using a screw gauge without any zero error the diameter of a wire determine as 2.74 mm . If the screw advances 5 mm when the thimble is given 10 complete rotations what are the possible valuses of the pitch scale reading circular scale reading and the least count if N is the number of head scale divisions?
