Question

All the distance of a curved surface is measured from the ​

Answer 1

For the measuring of length of a curved surface, first take the measure of length using a thread and then find out the numerical value of that length of thread using scale. This numerical value will give the length of the curved surface. Thus, both thread and scale are used to find out the length of a curved surface.
