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
 
        
                    
             
        
        
        
Answer:
2
Step-by-step explanation:
18-4^2=2
 
        
                    
             
        
        
        
Slope is generally showed by a variable, the variable can be represented by any letter. In this case the variable is represented by x
so the slope is the number that comes before the x, so the slope of this equation is -8
So your answer is A
        
             
        
        
        
X=6y
sum of their reciprocals
(1/x)+(1/y)=7
x=6y
1/6y+1/y=7
1/6y+6/6y=7
7/6y=7
times both sides by 6y
7=42y
divide both sides by 42
1/6=y
x=6y
x=6(1/6)
x=6/6
x=1
the numbers are 1 and 1/6
        
             
        
        
        
Answer:
So basically the mean is the average number. 
Step-by-step explanation:
add all of them then divide by 6 (aka how many fractions)
