Answer:
Area of shaded region ≈ 192.42
Step-by-step explanation:
21/2 = radius
radius = 10.5 m
A = πr squared
Area of shaded region≈346.36
10.5 - 3.5 = 7
Area of unshaded region ≈ 153.94
346.36 - 153.94 = 192.42
Answer:
y = -x + 15
Step-by-step explanation:
y = x-2
slope = 1
perpendicular line slope = -1
pass point (10, 5)
y intercept = y - mx = 5 - (-1)x10 = 15
equation: y = mx + b
y = -x + 15
sorry i cant solve this problem
maybe next time
hope you understand me!
