Area of semi circle: you know the radius is 5. 5^2 * pi = 25pi/2 = 12.5pi
For triangle: bh/2 = (10 * 10)/2 = 50
Add them together: 12.5pi + 50
12.5pi = 39.25
39.25 + 50 = 89.25
It’s closest to D

Answer:
Variable Y is equal to 7.5.
Step-by-step explanation:
First, open the brackets:
18 + 20y - 8 = -140

20y = -140 - 18 + 8
20y = -150
Third, divide by 20.
y = 7.5
