Answer:

141 in.^2

Step-by-step explanation:

First find the area of the full circle

The radii is 9 inches

A = pi r^2

A = 81 pi

Then find the area of the  next smallest circle which is 6 inches

A = pi r^2

A = 36 pi

Subtract the difference to get the area of the blue

81pi - 36 pi

45 pi

45 * 3.14

141.3

vaieri [72.5K]

Step-by-step explanation:

This can be modeled by the equation f(x)=7+5x

Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22

If x=50 then f(50)=7+5(50)

f(50)=$257

babunello [35]
First, 47.7-45 to get price increase by tax for I which is 2.7. next divide 2.7 by 45 and multiply that by 100 to get a sales tax of 6%. Next 37.7-35 is once again 2.7. divide 2.7/35 and multiply times 100 to get a sales tax of 7.7 for T. T=7.7% and I=6% so since 7.7>6, therefore Tennessee has a greater sales tax then Iowa
