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

ycow [4]

Answer:

$\delta d =$ +/- 0.01 mm

$\delta r =$ +/- 0.02 mm

Step-by-step explanation:

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

$\delta r$ . 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 $\delta r$ multiplying the diameter uncertainty by 2 ( $\delta r = 2*0.01=0.02$ ).
