Find Radius :
----------------------------------------------------------------
Radius of the semicircle = 10 ÷ 2 = 5cm
----------------------------------------------------------------
Find Area of the semi circle :
----------------------------------------------------------------
Area of the semi circle = 1/2 πr²
Area of the semi circle = 1/2 x π x (5)²
Area of the semi circle = 12.5π cm²
----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the inner circle = 5 ÷ 2 = 2.5 cm
----------------------------------------------------------------
Find area of inner circle :
----------------------------------------------------------------
Area of the inner circle = πr²
Area of the inner circle = π x (2.5)²
Area of the inner circle = 6.25π
----------------------------------------------------------------
Area of the shaded region :
----------------------------------------------------------------
Area of the shaded region = 12.5π - 6.25π
Area of the shaded region = 6.25π
Area of the shaded region = 19.63 cm²
----------------------------------------------------------------
Answer: Area of the shaded region = 19.63 cm²

Answer:
y=4x bc each one is 4 so for one box it cost $4
Answer:
$7.09
Step-by-step explanation:
Let wheat shipment be x bushels
Per bushel cost = 5.35
So x bushels cost = 5.35x
Achieving markup of 6% means 1.06 * 5.35x =5.671x
20% spoiled means 80% of x stays, so 0.8x will need to be sold at 5.671x
Selling price should be 5.671x/0.8x = $7.09
So that's 7 dollars and 9 cents
