3x
Step-by-step explanation:
 
        
                    
             
        
        
        
9.8t^2-49t+40=0
t=(49±√833)/19.6
t≈1.027, 3.97
1.027<t<3.97
        
                    
             
        
        
        
By definition, the volume of a cone is given by:
 V = (1/3) * (pi) * (r ^ 2) * (h)
 Where,
 r: cone radius
 h: height of the cone
 Substituting values:
 V = (1/3) * (3.14) * ((8/2) ^ 2) * (9)
 V = 150.72 cm ^ 3
 Answer:
 this paper cone cup can hold:
 V = 150.72 cm ^ 3
