For this case we have by definition, that the volume of a sphere is given by:
![V = \frac {4} {3} \pi * r ^ 3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%20%7B4%7D%20%7B3%7D%20%5Cpi%20%2A%20r%20%5E%203)
Where:
r: It is the radius of the sphere
If the radius is divided by 3 we have:
![\frac {r} {3}:](https://tex.z-dn.net/?f=%5Cfrac%20%7Br%7D%20%7B3%7D%3A)
![V = \frac {4} {3} \pi * (\frac {r} {3}) ^ 3\\V = \frac {4} {3} \pi * \frac {r ^ 3} {27}\\V = \frac {4} {81} \pi * r ^ 3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%20%7B4%7D%20%7B3%7D%20%5Cpi%20%2A%20%28%5Cfrac%20%7Br%7D%20%7B3%7D%29%20%5E%203%5C%5CV%20%3D%20%5Cfrac%20%7B4%7D%20%7B3%7D%20%5Cpi%20%2A%20%5Cfrac%20%7Br%20%5E%203%7D%20%7B27%7D%5C%5CV%20%3D%20%5Cfrac%20%7B4%7D%20%7B81%7D%20%5Cpi%20%2A%20r%20%5E%203)
ANswer:
the volume decreases considerably because the denominator increases
Answer:
D—
The histogram will have a horizontal or an x axis of time/minute intervals of the calls (5 minutes in each), and the vertical axis or y axis will be the number of calls made.
Since the cost is $6.75 per pound, and we have 2.6 pounds, multiply 6.75•2.6 to find the cost.
It would cost $17.55.
