Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object :
ground area ×height
the ground area of a cylinder is a circle, so it is
pi×radius² × height
the radius is always half of the diameter (of the diameter is airways twice the radius).
radius = 6/2 = 3 ft.
the volume is then
pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³
so, the answer is 81pi ft³.
Answer: 99.7 % of the bags contain between 62 and 86 potato chips.
Step-by-step explanation:
The standard deviation given is 4.
Find the difference between the given numbers and the mean,
74-62= 12 . 86-74=12
then divide 12 by 4 to find the number of standard deviations: 12/4=3
Check a chart or diagram of the Gaussian Distribution to find that 99.7% of the samples lie within 3 standard deviations from the mean.
A. 2x + 1 (2x is the "twice a number")
b. x - 6 (x is the number being decreased)
c. 2/3x
To find what percent of 1,200 is 9, you need to divide 9 by 1,200 and then move the decimal two places to the right.
9 / 1,200 = 0.0075
Moving the decimal two places to the right gives us 0.75, so now you add a percent sign to the end.
.75% of people said they wouldn't go to see the band again.
