The area of the square is 9 in^2

The side of a square is the square root of the area.

Side of square = √9 = 3 inches.

The side of the square is the diameter of the inscribed circle.

Circumference of a circle is PI x diameter.

Circumference of inscribed circle = 3.14 x 3 = 9.42 inches

The diameter for the circumscribed circle would be the diagonal of the square which is 3√2 =  ( Side length x √2) ≈ 4.2426

The circumference = 3.14 x 3√2 = 13.321

Find the ratio between the two circles:

Circumscribed / inscribed =

13.321 / 9.42 = 1.41

Answer:

b=\frac{1}{6}

Step-by-step explanation:

In f(x)=a\cos(b(x-c))+d, b represents a constant related to the period of the function. Here's how it's related:

b=\frac{2\pi}{T}, where T is the period of the function.

We're given T=12\pi, so solving for b:

b=\frac{2\pi}{12\pi}=\boxed{\frac{1}{6}}
