Answer:
$77.18
Step-by-step explanation:
A = total amount
P = principal
I = interest
A = P(1 + r/n)^n·t
A = 70(1+.05)²
A = 70(1.05)²
A = 77.175
I = A - P
  
        
                    
             
        
        
        
The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that
[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in
the answer is 
8 in
        
             
        
        
        
The diameter is given which is 13.5feet and radius is half of diameter. Therefore radius = 6.75 feet.
Slant height = 16.8 feet
The formula of surface area of cone is

Correct option is C 
 
        
             
        
        
        
You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m
        
                    
             
        
        
        
You have to subtract 12 from 50 to get 38 and multiply it by 12 (number of months) to get 456 eggs
