Answer:
81.12 cm²
Step-by-step explanation:
The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.
(3.14 * 4²)/2 + (14 * 8)/2 <em>(Work the operations in parentheses first.)</em>
(3.14 * 16)/2 + 112/2
50.24/2 + 112/2 (<em>Divide 50.24 by 2. Do the same for 112.)</em>
25.12 + 56 (<em>Add 25.12 & 56.)</em>
81.12 cm²
The area of the figure is 81.12 cm².
 
        
             
        
        
        
Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
=   %
 %
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
=     %
 %
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,    
 
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because,  
 
Therefore, Option B and F is correct only.
 
        
                    
             
        
        
        
A1 = 0.91
a6 = -0.14
sum = (0.91+-0.14) /2
sum = 2.31
