You should draw a picture to visualize the problem easier.

The circumference of inner circle = 44 ft
That means the radius of the inner circle:

2*pi*r = 44
r = 44/(2pi) = 22/pi

Using the picture you hopefully drew, we see that the radius of the outer circle:
22/pi + 2

To figure out the circumference of the outer circle:
2pi*(22/pi + 2) = 44 + 4pi

So how much bigger is the the circumference of the outer circle than the inner circle?

44 + 4pi - 44 = 4pi

It is 4pi bigger or 4 * (3.14) = 12.56 feet

(Write an equivalent expression by applying the distributive property X+2)(x+9)
ivann1987 [24]

Answer:

Step-by-step explanation:

(x + 2)(x +9)= x*(x +9) + 2*(x +9)

                   = x*x  + x*9  + 2*x + 2*9

                   = x² +<u> 9x + 2x </u>+ 18   {Combine like terms}

                    = x² + 11x  +18
