The pitch of a screw gauge is 1mm and its cap is divided into 100 divisions. When this screw gauge is used to measure the diameter of a wire, then main scale reading is 2 mm and 58^(th) division of circular scale coincides with the main scale. There is no zero error in the screw gage. Then the diameter of the wire is

A screw gauge with a pitch of 1 mm has 100 divisions on its circular scale. What it is used to measure the diameter of a thin wire, the main scale reading is 3 mm and the circular scale reading is 45. If D is the diameter of the wire in mm, then find the value of D.

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)
