Answer:
Step-by-step explanation:
Statements                          Reasons
----------------------------------------------------------------
1. ∠V ≅ ∠Y                        Given
2. WZ bisects ∠VWY          Given
3. ∠VWZ ≅ ∠YWZ            Definition of Angle Bisector (2)
4. WZ ≅ WZ                         Reflexive Property
5. ΔVWZ ≅ ΔYWZ               AAS Theorem (1,3,4)
**In case you didn't know the definitions**
Angle Bisector - A line, segment or ray that divides an angle into two congruent angles
Reflexive Property - X = X
AAS Postulate -  If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangle's are congruent
 
        
             
        
        
        
Volume of A= πR².H ==> V(A)=4π m³
Volume of V =πR².H ==>V(B)=8π m³
.Ratio of A to B =(4π) /(4π) = 1/2
        
                    
             
        
        
        
99.60 or 100.00? I haven’t done this for a longgggg time
        
                    
             
        
        
        
Diameter is 9 inch so the radius is 9/2=4.5inch
Part A: 2πr=28.26inch
π=28.26/(2r)
π=28.26/(2*4.5)=3.14
Part B: πr^2=63.585inch
π=63.585inch/(4.5inch)^2
π=3.139753086 
Part C: Both of the answers are correct but Part B is more percise because it has more significant figures.
