D because the shaded region has one side and subtract by pie and substitute to get this answer.
Answer:

Step-by-step explanation:
Circumfereince=pid
pi=3.14 for now
d=diameter
d=12
C=12*3.14
C=37.68 m
answer is 37.68m
if you wanted more acurite, then find to the thoustadth and round (you would ge 37.692 )
To find this answer, you must first find out how much each car makes them. You do 144 divided by 24 to do this. You get the answer 6. Which means that they make $6 for each car washed.
Now that you know how much each car wash makes them, you multiply 6 by 30 to get how much they earned on Sunday.
6 x 30= 180.
So, they earned B.$180 on Sunday
