What is the approximate area of shaded region 2 (between circles A and B)? Consider the segmented circle B that you chose. What is the Interior angle of each sector inside your circle B? What is the approximate area of each sector in your circle B?

b) 36

step-by-step explanation:

18 times 2 is 36

0.038

step-by-step explanation:

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
