500=4πr^2. first divide 500 from four which will equal 125, then divide 125 with π and it will equal 39.788 . finally √39.788. the answer will be r=6.3 or 6
        
             
        
        
        
Answer:
If you are reffering to GCF then the GCF would be explained like this
    Find the prime factorization of 18
    18 = 2 × 3 × 3
    Find the prime factorization of 60
    60 = 2 × 2 × 3 × 5
    To find the gcf, multiply all the prime factors common to both numbers:
    Therefore, GCF = 2 × 3
    GCF = 6
 
        
                    
             
        
        
        
        
Multiply 1/3 by any number higher than 2 and you can have equivalent fractions.
Ex:
1/3×3/3=3/9
