The volume is equal to $98,470.4\ cm^{3}$

Step-by-step explanation:

step 1

Find the radius of the base of cylinder

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=87.92\ cm$

assume

$\pi =3.14$

substitute and solve for r

87.92=2(3.14)r

$r=87.92/[2(3.14)]=14\ cm$

step 2

Find the volume of the water tank (cylinder)

The volume is equal to

$V=\pi r^{2} h$

we have

$r=14\ cm$

$h=160\ cm$

assume

$\pi =3.14$

substitute

$V=(3.14)(14)^{2} (160)$

$V=98,470.4\ cm^{3}$

Answer from: Quest

see below

step-by-step explanation:

7. there are 10 data points in the set. the middle point is between 5 and 6. the middle point in the top half is 8 and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term point 8 = 100 point 3 = 88

iqr = 100-88 = 12

final point 8 = 93 point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6. b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical . there is an outlier for the males that skews the data

5. the iqr is a better measure of spread for the movies and basketball games. since the basketball game has an outlier, we do not want to use standard deviation for measurement.

3. the exam median is much higher than the class median. the median line is farther to the right on the exams

2. there is no way to tell what the means are from the box and whisker plots.

Answer from: Quest

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is $3\times 8.50=$25.5$

cost of 2 dresses if one cost at $27.50 is $2\times 27.50=$55$

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is $25.5+$55+$17.50=$98
