It could be 1 and 18, 2 and 9, 3 and 6
Step-by-step explanation:
It depends on what the width is
 
        
                    
             
        
        
        
Interesting question about feet and inches.  The best way to solve this problem is to ask yourself how many inches are in a foot.  Since there are 12 inches in every foot then the length of 2'8" can be written as (2*12)" + 8".  Which is 24+8 or 32 inches.  The second number (1'6") can be written as (1*12)"+6" which is 18 inches.  32 + 18 = 50 inches.  Or, if you want to change this back into feet and inches just divide it by 12.  50/12 is 4 R. 2.  So 4'2".
        
             
        
        
        
Circumference 
2*pi*r
2*(22/7)*(9/2)
2*(11/7)*9
198 / 7
28.28 cm
so 56.52 is not correct
        
             
        
        
        
Answer:
The diameter of the circle is 9.
Step-by-step explanation:
Because circumference is equal to  * d, we can backtrack and use this equation to find diameter. Let's say
 * d, we can backtrack and use this equation to find diameter. Let's say  is equal to 3.14.
 is equal to 3.14.
28.26 = 3.14d
Divide both sides by 3.14.
9 = d
The diameter of the circle is 9.
 
        
             
        
        
        
You can solve this using trigonometric functions.
The angle between the fish and the ground is
tan θ = 100 / 50
θ = tan-1 (2)
θ = 63.43°
The height of the bird before it dropped the fish is already given, which is 100 yards.
