Answer:
Largest volume in terms of r =  4r^3π/ 3√3 or you could write it as  4√3r^3π/9.
Step-by-step explanation:
 
        
             
        
        
        
It is a mixed number because 12/2 can be written as 6 instead of 12/2
        
                    
             
        
        
        
z = 37°
Step-by-step explanation:
The exterior angle theorem says that the sum of two internal angles is equal to the exterior angle
In this case the sum of z and z+4 will be equal to z+41
Writing mathematically

Hence
z = 37°

So the question ask to find and calculate the vector parametric equation r(t) for the line through the points P=(1,0,-2) and Q(1,5,1) for each given condition. And the possible vector parametric equation is <1,2,-2>+t/4<1,5,3>. I hope you are satisfied with my answer and feel free to ask for more
