Step-by-step explanation:
here is your answer 
 
        
             
        
        
        
21:30 and 35: and 50 this is because 7 times 3 is 21, 10 times 3 is 30, and 7 times 5 is 35, and lastly 10 times 5 is 50
        
                    
             
        
        
        
Equal sets have the exact same elements, so they must have the same number of elements. Therefore, equal sets must also be equivalent. No, not all equivalent sets are also equal sets
        
             
        
        
        
Answer:
Volume = 1330.6cm³
Step-by-step explanation:
Step one 
 This problem bothers on the mensuration of solid shapes a cylinder. 
We know that the volume of a cylinder is expressed as
V= πr²h
Step two 
Given data 
Base of the cylinder /diameter = 11cm
Hence radius = 11/2= 5.5cm
Length /height of cylinder = 14cm
Step three 
Substituting our given data we have
Volume = 3.142*(5.5)²*14
Volume = 3.142*30.25*14
Volume = 1330.637cm³
to 1 decimal place we have
Volume = 1330.6cm³
 
        
             
        
        
        
Answer:
