Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
 
        
                    
             
        
        
        
Answer:
= 18 cubic inches
Step-by-step explanation:
The volume of a cone is given by the formula;
V = 1/3 × base area × height 
While that of cylinder is given by the formula;
Volume = Base area × height 
Since we need the cylinder to fit exactly inside the cone, then it  means that their bases are the same and heights are the same.
Therefore;
The cone has three times less volume compared to the cylinder.
Thus;
Volume of the cylinder = Volume of cone × 3
                                        = 6 In³ × 3
                                        <u>= 18 cubic inches</u>
