Answer:
80π
Step-by-step explanation:
Circle O with radius IO:
large radius = IO = 12 = R
Circle O with diameter JK
IJ = JK = KL = 2 × IO = 24
IJ = JK = KL = 24/3 = 8
small radius = 8/2 = 4 = r
The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.
That is the same as
1 semicircle of radius 12 plus 1 semicircle of radius 4
A = πR²/2 + πr²/2
A = π(12² + 4²)/2 
A = 160π/2
A = 80π
 
        
             
        
        
        
The answer is 39 because 6 times 5 is 30. 30 plus 9 is 39. :)
        
                    
             
        
        
        
Answer:
O weight in kilograms = 25 x 3.5 ÷ 2.2
Step-by-step explanation:
As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.
Therefore, the total number of pounds for the 25 packages = 
3.5 pound packages × 25
= 87.5 pounds 
We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.
Note that:
2.2 pounds = 1 kg
Hence:
87.5 pounds = 
= 87.5÷ 2.2
= 39.772727273 kg 
He needs to buy 39.772727273kg from the wholesaler
 
The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is: 
O weight in kilograms = (25 x 3.5) ÷ 2.2
 
        
             
        
        
        
Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)
