9b-27= 3(2b-8)+2b solve for b

please show work on how you found b

 b = 3

Step-by-step explanation:

9 − 27 = 3(2 − 8) + 2

9 − 27 = 6 − 24 + 2

9 − 27 = 6 − 24+ 2

9 − 27 = 8 − 24

9−27=8−24

9−27+27=8−24+27

9 = 8 + 3 Subtract 8b from both sides

b = 3

The formula for area of a circle is: πr^2

r is half the diameter.

FE is the diameter: r = 20/2 = 10

Area of circle using FE = π10^2 = π * 100 = 314 square meters.

BE is a radius:

Area = π3.5^2 = π * 12.25 = 38.465  = 38.5 square cm ( rounded to nearest tenth).

AB is a radius:

Area = π11^2 = π * 121 = 379.94 = 380 square feet ( rounded off).

EF is a diameter

r = 12/2 = 6 meters

Area = π6^2 = π * 36 = 113.04 = 113 square meters ( rounded off).
