A)  
Step-by-step explanation:
 
        
                    
             
        
        
        
KE = 1/2(m * v^2)
KE = 1/2(1350 * 12^2)
KE = 1/2(1350 * 144)
KE = 1/2(194,400)
KE = 97,200 Joules

Step-by-step explanation:
The area that cow can graze is in the form of semicircle.
Radius of semicircle
Length of rope =14 m
Required area = 1/2 ×πr 
=1/2×22/7×r^2
=1/2×22/7×14×14
=308m2
 
        
             
        
        
        
<u>Corrected question :</u>
Solve the equation. Write your answer as an integer or simplified fraction.
<u>Required Solution :</u>
The given equation, 
★ Multiplying -7 into (n - 2), 
>> 8n - 7 × (n - 2) = 18
>> 8n - 7n + 14 = 18
★ On substracting 7n from 8n we gets, 
>> n + 14 = 18 
★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14), 
>> n = 18 - 14 
>> n = 14
★ Therefore,
