pentagon [3]

Answer:

h = 39

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the volume is 10000pi and the diameter is 32

The radius is 32/2 = 16

10 000 pi = pi (16)^2 h

Divide each side by pi

10 000 pi/pi = pi/pi (16)^2 h

10 000= 256 h

Divide each side by 256

10000/256 = 256h/256

39.0625 = h

To the nearest whole number

h = 39

n200080 [17]

bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm

<u>Step-by-step explanation:</u>

Here we have , A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 13 cm with a standard deviation of 0.10 cm. We need to find For what lengths will a bolt be destroyed .Let's find out:

A manufacturer of bolts has a quality control policy that requires it destroy any bolts that are more than 2 standard deviations from the mean.

mean length= $13 cm$

standard deviation= $0.10 cm$

2 standard deviation from mean= $13 \pm (2(0.10))$

Therefore, bolts of length more than $13+0.2$ , and less than $13-0.2$ will be destroyed

= 13.20 cm and 12.80 cm
