The volume of the solid generated when the right triangle below is rotated about side is 564.2.
<h3>How to calculate the volume?</h3>
The volume will be calculated by using the formula:
= 1/3πr²h
where, r = 7
h = 11
Therefore, the volume will be:
= 1/3πr²h
= 1/3 × 3.14 × 7² × 11
= 564.2

False, just because they have a same base doesn't mean they are exactly the same. Remember a cylinder has parallel bases that are congruent and a cone does not have that. <span />
Answer:
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
And for this case we select a sample size of n= 81. Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
And the standard error of the mean would be:
4.1.5
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

You have to divided 11 by 2 in order to get the radius
And you’ll get 5.5
r=5.5
h=12
Your formula is (1/3)(pi)(r^2)(h)
