Answer:
It is the second picture.
Step-by-step explanation:
Answer: d=-3
-7d+8<29
-8 -8
-7d<21
-7d/-7<21/-7
d<-3
Formula for the area of a circle: A = pi * r^2
A semi-circle is half of a circle. So, we will need to divide the area of the total circle by 2 to find the area of a semi-circle.
r = d / 2
r = 6 / 2 = 3
A = pi * 9
A = 9pi
Semi-circle:
A = 9pi / 2
A = 4.5 pi cm^2 or 14.14 cm^2
Hope this helps!! :)
