Answer:
A = 49 in^2
Step-by-step explanation:
The perimeter of a square is found by
P = 4s where s is the side length 
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want to find the area
A = s^2 where s is the side length
A = 7^2
A = 7^2
A = 49 in^2
 
        
                    
             
        
        
        
Answer:
The value for r is 19.1 cm
Step-by-step explanation:
We have been given that  s = 16 cm, θ = 48° and we have to find the radius r.
We know the relation

Hence, first of all convert the angle in radian
θ = 48°= 0.837758 radian
Therefore, we have
