Answer:
1 in. is the answer.
Step-by-step explanation:
Solution: A Rectangle ABDE in which DE=4 inches and BD= 6 inches
  There are two kinds of rotations
1. one along the Breadth, side having length 6 inches,i.e rotated along line GH,  Cylinder Z is created.
Radius of cylinder Z=6/2= 3 inches
2. Second along the Length, Side having length 4 inches,i.e rotated about a line CF, cylinder Y is created.
Radius of cylinder Y= 4/2= 2 inches
Difference in Radii= Radius of cylinder Z  -  Radius of cylinder Y
                               =  3 - 2= 1 inches
Diagram shown below of both the cases:
 
        
                    
             
        
        
        
Answer:
<h2>x = 10√3</h2>
<u>Step-by-step explanation:</u>
cos 45° = base / hypotenuse
1/√2 = base / 15√2
15√2 = base√2
Base, = 15
sin 60° = perpendicular / hypotenuse
hypotenuse = x
√3/2 = 15 / x 
x √3 = 30
x = 30 / √3
x = 10√3
