The perimeter = 4 * length of a semicircle of radius 5 == 4* pi * 5 = 20 pi cm
The area of one of the clear parts = 1/2 area of square - area semicircle
= 1/2 * 10^2 - 1/2 pi *5^2 = 50 - 12.5pi
So area of shaded parts = area of square - 4 (50 - 12.5pi)
= 100 - 200 + 100pi = (100pi - 100) cm^2
Answer:
$10 per kilogram
Step-by-step explanation:
To eliminate the decimals,multiply everything by 10
0.4.........4

Answer: 110
Reasoning: all of the numbers should add up to 360.
140+110=250
360-250=110
The angles of 110 look the same, go for it.
