The radius of the cylindrical vase is 8 centimeters, if the cylindrical vase holds 8,038.4 cubic centimeters of water and the height of the vase is 40 centimeters.
Step-by-step explanation:
The given is,
                  Volume of cylindrical vase = 8038.4 cubic centimeters
                  Height of the cylindrical vase = 40 centimeters 
Step:1
                 Formula for volume of cylindrical vase,
                                       ......................(1)
......................(1)
                Where, r - Radius of cylindrical vase
                            h - Height of cylindrical vase  
                 From the given,
                                       V = 8038.4 cubic centimeters
                                       h = 40  centimeters  
                 Equation (1) becomes,
                              8038.4 
                                            (∵
                                (∵  = 3.14 )
 = 3.14 )
                                
                                        
             
                                        
                                         r = 8 centimeters
Result:
            The radius of the cylindrical vase is 8 centimeters, if the cylindrical vase holds 8,038.4 cubic centimeters of water and the height of the vase is 40 centimeters.
 
        
             
        
        
        
Clearly, alternative B
y = 0.01x + 7.5
y = (0.01)*5000 + 7,5
y = 50 + 7.5
y = 57.50
