Answer:
h = 9x
Step-by-step explanation:
Given: i. for the cylinder, base radius = 2x cm, height = h cm
            ii. for the sphere, radius = 3x cm
            iii.  volume of the cylinder = volume of the sphere
volume of a cylinder is given as;
volume = 

 h
h
where: r is its base radius and h the height
volume of the given cylinder = 
 x
 x  x h
 x h
                                               = 
 x 4
 x 4 x h
 x h
                                               = 

 h
 h
volume of a sphere = 


 where r is the radius.
volume of the given sphere =  
 x
 x 
                                          =  
 x 9
 x 9 
                                          = 12

Since,
volume of the cylinder = volume of the sphere
Then we have;
 

 h = 12
 h = 12

 4
 h = 36
 h = 36

subtract  from both sides
 from both sides
 4 h = 36
h = 36 x
x
divide both sides by 4
h = 
   = 9x
h = 9x
 
        
             
        
        
        
The astroid is 100,000,000 miles away.
It's traveling at a speed of 100,000 miles per day.
100,000,000 ÷ 100,000 = 1,000
1,000 days.
