When finding the volume of this shape, there would practically be a formula that we would have to use, in order to solve this on how we are suppose to do.

We know that the radius would then be 4, and therefore, we would just plug this in into the formula which would be illustrated below.

$\boxed{V= \frac{4}{3} \pi r^3}$

All we would have to do, is to plug the number 4 into the proper location in the formula.

In a decimal form, your correct answer would then be 268.08.

By as we can see above, we would have to convert the decimal form, into a fraction form, and this would be shown below.

$\left[\begin{array}{ccc}\boxed{3*8=24-8=256/3}\end{array}\right]$

Your correct answer should be (option a)

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:

Montano1993 [528]

Answer:

$0.2$ miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.

Step-by-step explanation:

As there is no graph mentioned here but the information are quite sufficient to answer the question.

We have points $(0,3), (5,4),(10,5)...$

From these points we can find the slope of the line .

From point slope formula $y-y_1=m(x-x_1)$

And assigning $(x,y) (0,3)$ and $(x_1,y_1) (5,4)$

$m=\frac{y_1-y}{x_1-x} =\frac{4-3}{5-0} =\frac{1}{5}=0.2$

This slope is also the speed of the bird which is $0.2\ miles\ per\ minute.$

As by plugging the values of any coordinate point we can confirm this.

Lets put $(10,5)$ , y-axis is the distance so in $10$ minutes the the distance covered by the bird must be equal to to y-axis value which is $5$ miles.
