Answer:
The answer is 56.52 square centimeters
Step-by-step explanation:
The area of a circle is Pi R^2 so that means the area of a semi circle is half of that which is Pi R^2/2
since diameter is 12, radius = 12/2 = 6
Area = (3.14 × 6^2)÷2 = 56.52
First do 48.50-21 then divide that amount by 5. Then that’s how much each pair of socks cost so
48.50-21=27.50
27.50%5=$5.50 so rx=$5.50
