Which of the following measurement is more accurate?

The figure below shows quadrilateral ABCD. What is the measure of /_C ?

The diagram below shows part of the main scale and vernier scale of a vernier calipers, which is used to measure the diameter of a metal ball. Find the least count and the radius of the ball. .

Let us now use a millimeter scale (on which millimeter marks are there). This is also our normal meter scale which we use in our routine life. From the figure, we can see that length AB is more than 3.3 cm and less than 3.4 cm. If we note down the length, l= AB = 3.4cm. Then, this measurement has two significant figures 3 and 4 in which 3 is absolutely correct and 4 is reasonably correct (doubtful). Least count of this scale is 0.1 cm because this scale can measure accurately only upto 0.1 cm. Further, maximum uncertainly or maximum possible error in l can also be 0.1 cm.
