Problem 2E

A measurement of the circumference of a disk has an uncertainty of 1.5 mm. How many measurements must be made so that the diameter can be estimated with an uncertainty of only 0.5 mm?

Step-by-Step Solution:
Step 1 of 3

Solution 2E

Step1 of 2:

We have A disk and let X be the measurement of the circumference of a disk has an uncertainty of 1.5 mm. Let Y be the measurement of the diameter of a disk has an uncertainty of 0.5 mm.

That is .

We need to find How many measurements must be made so that the diameter can be estimated with an uncertainty of only 0.5 mm.

Step2 of 2:

Consider

The circumference of disk is given by C = Where

C = circumference mathematical constant and its value is 3.14

= = = 0.25

Now,

C...
