Answer:

A: -6

Step-by-step explanation:

Flip around the question

what is 12 - 18

If you count the numbers in between 12 and 18

You get 6

So now just make the answer negative

There is not enough information to answer this question, the number of animals the captain has does not correspond to his age. For example, if a kid owned 20 chickens, there is no correspondence to his or her age, no one would know based on the quantity of possession.

Find the area of A cylinder has a volume of 175 cubic units and a height of 7 units. The diameter of the cylinder is

damaskus [11]

To find the area of the cylinder we need to find its volume first. Remember that the formula for the volume of a cylinder is $V= \pi r^{2} h$
where:
$V$ is the volume
$r$ is the radius
$h$ is the height
From the question we know that $A=175$ and $h=7$ . Lets replace those values in our volume formula:
$175= \pi r^{2} 7$
Now we can solve for $r$ to find our radius:
$r^{2} = \frac{175}{7 \pi }$
$r^{2} = \frac{25}{ \pi }$
$r= \sqrt{ \frac{25}{ \pi } }$
$r= \frac{5}{ \sqrt{ \pi } }$

Now that we know the radius, we can use the formula for the area of a cylinder $A=2 \pi rh+2 \pi r^{2}$
where:
$A$ is the area
$r$ is the radius
$h$ is the height
We know now that $r= \frac{5}{ \sqrt{ \pi } }$ and $h=7$ , so lets replace those values in our area formula:
$A=2 \pi ( \frac{5}{ \sqrt{ \pi } } )(7)+2 \pi ( \frac{5}{ \sqrt{ \pi } })^{2}$
$A= \frac{70 \pi }{ \sqrt{ \pi } } +50$
$A=174.07$

We can conclude that the area of a cylinder that has a volume of 175 cubic units and a height of 7 units is 174.07 square units.
