V=(4/3)pir^3
4.5pi=(4/3)pir^3
divide both sides by pi
4.5=(4/3)r^3
times 3/4 both sides
3.375=r^3
cube root both sides
1.5=r
radius is 1.5cm
        
                    
             
        
        
        
Answer:
C = 50.24
A = 7,925.540864 (Round to whatever you want)
Step-by-step explanation:
c = 2πr
c = 2(3.14)(8)
c= 50.24 
A = πr^2
A = (3.14)(50.24)^2
A = 7,925.540864
 
        
                    
             
        
        
        
9900  because you divide 99000 by 10
        
                    
             
        
        
        
Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length),  (x+y) (width), and (x-y) (height)
