Answer 2

AB = BC = CD = DE

AD = AB + BC + CD
AD = AB + AB + AB
AD = 3*AB
AD = 3*3
AD = 9

AE = AB + BC + CD + DE
AE = AB + AB + AB + AB
AE = 4*AB
AE = 4*3
AE = 12

-------------------------------------------------------

Now find the area of 2 circles

The first smaller circle has a radius of 9
The next larger circle has a radius of 12

After you get the areas, subtract them to get the area of the black ring
