Answer:
24 , 9.333333, 36, 13.3333333
Step-by-step explanation:
12+12=24
28/3=9.3333333333333 (doesn't matter how many you put bc it repeating)
12+12+12=36
40/3=13.3333333333333333 (doesn't matter how many you put bc it repeating)

Step-by-step explanation:
Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2
