Answer:
<h2>Diameter = 6 cm</h2>
Step-by-step explanation:
The formula of a volume of a sphere:
![V=\dfrac{4}{3}\pi R^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20R%5E3)
We have V = 36(3.14) cm³ = V = 36π cm³. Substitute:
<em>divide both sides by π</em>
<em>multiply both sides by 3</em>
<em>divide both sides by 4</em>
![R^3=27\to R=\sqrt[3]{27}\\\\R=3\ cm](https://tex.z-dn.net/?f=R%5E3%3D27%5Cto%20R%3D%5Csqrt%5B3%5D%7B27%7D%5C%5C%5C%5CR%3D3%5C%20cm)
The diameter D = 2R.
Therefore D = 2(3 cm) = 6cm
We conclude that she needs to route 10 phone calls to spend a total of 20 minutes in the phone (assuming that the unit rate does not change).

How many phone calls does Aaliyah have to route to spend a total of 20 minutes on the phone?</h3>
First, we know that she spends 10 minutes on the phone while routing 5 phone calls.
Then the unit rate is:
(5 phone calls)/(10 min) = 0.5 phone calls per min.
Now, if she spends 20 minutes, the number of phone calls that she will route (assuming that the unit rate does not change) is:
N = (0.5 phone calls per min)*20 min = 10 phone calls.
We conclude that she needs to route 10 phone calls to spend a total of 20 minutes in the phone (assuming that the unit rate does not change).

Answer:
x = 42
Step-by-step explanation:
2/7x = 12
Divide 2/7 from both sides
x = 12 / (2/7) = 12 * 7/2 = 42
