Wait how would you even do this?
Answer:
18/20π
Step-by-step explanation:
81π ÷ 1 = 81π
81π ÷2 = 18/20π
You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.
Answer:
The formula 
Step-by-step explanation:
<em><u>Explanation</u></em>
Given W = x² - 2 y z
2 y z = x² + W
Dividing '2z' on both sides , we get

⇒ 
Answer:
There are no real solutions to this equation.

Answer:
Given the radical form: 
Use the exponent rules:
![\sqrt[n]{a^m} = (a^m)^{\frac{1}{n}} = a^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5Em%7D%20%3D%20%28a%5Em%29%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%20%3D%20a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
we can write
as:

then;
= 
Therefore,
in exponential form is
