To calculate the volume of a cylinder, we have equation like this: v = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. we can measure the diameter (r = d 2 ) and height directly. to calculate the confidence interval of the volume, we should use the propagation of errors. we use the micrometer screw to measure the diameter. the minimum interval on the screw is 0.01mm. what is the confidence interval for δd and δr?

+/- 0.01 mm

+/- 0.02 mm

Step-by-step explanation:

. The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

. The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate  multiplying the diameter uncertainty by 2 ().

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
