the answer is the first one A
Total volume is volume of cylinder+volume of cone
Volume of cylinder=pi*r^2*h
V=pi*6^2*14
V=1582.56
Volume of cone=pi*r^2*h/3
V=pi*6^2*6/3
V=226.08
1582.56+226.08=1808.64 or 1808.6 cubic inches
Answer:
4.5 is a rational number, as it can be represented as 9/2. Many important numbers in mathematics, however, are irrational, and cannot be written as ratios.
The relationships that could have a negative correlation are as follows:
- the speed of a train and the length of time to reach the destination
- number of hours worked and free time
- speed of a car and minimum stopping distance
<h3>What is negative correlation?</h3>
Correlation between two variables shows the relationship between the two variables.
A positive correlation means that both variables move in the same direction i.e. as one increases, the other increases.
However, a negative correlation means that both variables are inversely related i.e. one increases as the other decreases.
Therefore, the relationships that could have a negative correlation i.e. inversely related are as follows:
- the speed of a train and the length of time to reach the destination
- number of hours worked and free time
- speed of a car and minimum stopping distance

Given:
The ratio is 
.
To find:
Inverse tangent of the given ratio.
Solution:
We know that,
Inverse tangent of the ratio = 
= 
Using scientific or graphing calculator, we get
Inverse tangent of the ratio = 
Round to the nearest degree
Inverse tangent of the ratio 
Therefore, the correct option is C.
