An oil storage tank is a cylinder with a height of 50 feet and a diameter of 20 feet. What is the volume of the tank? Use 3.14 for Pi. A cylinder has a height of 50 feet and diameter of 20 feet. 15,700 cubic feet 39,250 cubic feet 62,800 cubic feet 78,500 cubic feet

  15,700 cubic feet

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr²h

where r is the radius (half the diameter), and h is the height.

Put the given numbers into the formula and do the arithmetic.

  V = (3.14)(10 ft)²(50 ft) = 15,700 ft³

__

An estimate of the arithmetic will get you to the right answer choice:

  πr²h = π(100)(50) = 5000π ≈ 3×5000 = 15,000 . . . . close to 15,700

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.
