I'm going to assume the crust covered by the dosenot matter because the total surface area cannot be found without the depth of the pie.
So the surface are is the area of the top of the pie, the top of the pie is circular and is equal to 2

r²
The diameter is the sum of 2 radii, hence r=8
D=12
  = 2r =12
r=8
With the raduis the area can be found
A= 2

r²
A=2

8² 
A=2(64)

A=128

If the pie cost 10.99, the cost per inch can be found by dividing the area by cost
cost/inch =128 

/10.99
cost/inch =11.64

               = 11.64(3.14)
               = 36.57
The pie costs 36 cents per square inch
 
        
        
        
Answer:
D
Step-by-step explanation:
The correlation coefficient r=-0.84 denotes that there is inverse relationship between x and y. It means that as the x values increase the y values decrease whereas as the x values decreases the y-values increases. Also, r=-0.84 denotes the strong relationship between  x and y because it is close to 1. So, r=-0.84 denotes that there is strong linear relationship between x and y with smaller x values tending to be associated with larger y values.
 
        
             
        
        
        
Answer:
The number is 24
Step-by-step explanation:
Let x = number
Add 16 to the number
x+16
Is equal to 40
x+16 = 40
Subtract 16 from each side
x+16-16 = 40-16
x = 24
 
        
             
        
        
        
Your molarity would be 0.975 M HCl because it’s moles of solute divided by liters of solvent 
 
        
                    
             
        
        
        
If i simplify number 6 it would be -55/63
