Answer:
V = 267.9 in^3
Step-by-step explanation:
V = 4/3 * (pi) * r^3
V = 4/3 * 3.14 * 4^3
V = 4/3 * 3.14 * 64
V = 256/3 * 3.14
V = 803.84/3
 
        
             
        
        
        
<u>Answer:</u>
x = ±5
<u>Step-by-step explanation:</u>
We are given the following polynomial function and we are to find all of its real roots:

Let  so we can now write it as:
 so we can now write it as:

Factorizing it to get:



Substitute back  to get:
 to get:

 
The quadratic factor has only complex roots. Therefore, the real roots are x = ±5.
