Vcylinder=hpir^2
Vcone=1/3hpir^2

vcone
h=6
r=3/2=1.5
v=1/3*pi*6*1.5^2
V=2pi*2.25
V=4.5pi

vcylinder
r=3/2=1.5
h=5
v=5*pi*1.5^2
v=5pi*2.25
v=11.25pi

minus

A-B=4.5pi-11.25pi=6.75pi

aprox pi=3.141592
diference is21.205
round

21.2

Solutions

Volume is the measure of the amount of space inside of a solid figure. To solve the question we have to use the formula's for a cone and cylinder.

Volume of cylinder =hπ²
Volume of cone =1/3hπ²

Solve

Volume of cone
Formula = 1/3hπ²

height = 6
r = 3/2=1.5
v=1/3×π×6×1.5^2
V=2π×2.25
V=4.5pi

Volume of cylinder
formula =hπ²

r=3/2=1.5
h=5
v=5×π×1.5²
v=5π×2.25
v=11.25π

Subtraction

A-B=4.5π -11.25π=6.75π

π =3.141592

= 21.205

rounded = 21.2

Answer from: Quest

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

Answer from: Quest

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
