B because 6 times 2 is 12...
        
                    
             
        
        
        
The perimeter of the square is calculated through the equation,
                                        4x = P
where P is the perimeter and x is the measure of the sides.
When P is 32 units then,
                                         32 units = 4(x)
                                                 x = 8 inches
This 8 inches is the diameter of the cylinder formed by the rotation. 
The circumference of the base is calculated through,
                            C = 2πr = πD
Substituting the known values,
                              C = π(8 units) = <em>8π units
</em><em></em>When π is equal to 3.14, we solve for the numerical value of the cylinder as follows,
<em>                                      C = 8(3.14) = 25.12 units
</em><em></em>Thus, the figure formed is a cylinder with base circumference equal to 25 units. The answer is the third choice. <em>

X1 = 0
X2 = 1
X3 = 7
I hope that helps!! :)
        
                    
             
        
        
        
It's an angle. That should work because it's obvious. Hope it helped.
